step 201: and for each position point of a target reservoir of the target oil and gas block, acquiring an attribute value corresponding to each seismic attribute in the plurality of seismic attributes at the corresponding position point.

The target reservoir of the target oil and gas block refers to a reservoir to be researched, before a new well is deployed in the target oil and gas block, the target reservoir of the target oil and gas block can be researched to determine oil and gas distribution in the target reservoir, and a basis is provided for deploying the new well in the target oil and gas block according to the determined oil and gas distribution in the target reservoir.

It should be noted that the target reservoir is a plane, and the plane may be composed of different points, so that the research on the target reservoir may be decomposed into a plurality of location points composing the target reservoir. In practical applications, the plurality of location points comprising the target reservoir may be determined by seismic exploration operations performed on the target hydrocarbon block.

The attribute value corresponding to the seismic attribute is converted data obtained by mathematically converting the post-stack seismic data volume, and the converted data includes geometric, kinematic, kinetic, or statistical characteristics related to the seismic wave. In practical application, the attribute value corresponding to each seismic attribute in the plurality of seismic attributes at each position point of the target reservoir may be obtained by user input, may be obtained by transmission from other devices, and may also be obtained by performing mathematical transformation on the post-stack seismic data volume through commercial seismic interpretation software. For example, a post-stack seismic data volume of a target reservoir of the target oil and gas block is obtained, and mathematical transformation is performed on the post-stack seismic data volume by using a seismic attribute interpretation module built in Landmark seismic comprehensive interpretation software, so that an attribute value corresponding to each seismic attribute of a plurality of seismic attributes at each position point of the target reservoir is obtained.

It should be noted that after the post-stack seismic data volume is mathematically transformed, attribute values corresponding to a plurality of seismic attributes can be obtained, and the plurality of seismic attributes can be divided into a plurality of types according to wave kinematics and dynamics, which are respectively: the reservoir stratum seismic data acquisition system comprises eight categories of attributes including an amplitude category attribute, a waveform category attribute, a frequency category attribute, an attenuation category attribute, a phase category attribute, a correlation category attribute, an energy category attribute, a proportion category attribute and the like, wherein each category of attributes comprises seismic attributes with different quantities, and each seismic attribute can represent geological characteristics of a target reservoir stratum. For example, table 1 shows one possible partitioning of multiple seismic attributes by wave kinematics and dynamics. See table 1, where the first column is a type of seismic attribute and the second column is a seismic attribute contained in each of a plurality of seismic attribute types.

TABLE 1

In practical application, all seismic attributes shown in table 1 may be obtained, a target reservoir of a target oil and gas block may be studied through an attribute value corresponding to each seismic attribute in all seismic attributes, or a part of seismic attributes in all seismic attributes shown in table 1 may be obtained according to an actual production condition of the target reservoir of the target oil and gas block, and a target reservoir of the target oil and gas block may be studied through an attribute value corresponding to each seismic attribute in the part of seismic attributes, which is not specifically limited in this embodiment of the present invention.

After the attribute value corresponding to each seismic attribute in the plurality of seismic attributes at each location point of the target reservoir is obtained in step 201, a fusion weight of each seismic attribute in the plurality of seismic attributes may be determined through steps 202 to 205, where the fusion weight of each seismic attribute in the plurality of seismic attributes is used to represent the importance degree of the corresponding seismic attribute in the seismic attribute fusion process, and the fusion weights of the seismic attributes in the plurality of seismic attributes are different.

Step 202: a first test capacity for each of a plurality of production wells commissioned within the target hydrocarbon block is obtained.

The first productivity test refers to testing the maximum production capacity of the production well in the target reservoir under the specified bottom hole flowing pressure to obtain the corresponding productivity of the production well under the bottom hole flowing pressure.

For example, in the target reservoir, the productivity of a plurality of production wells may be tested by using the specified bottom hole flowing pressure, and the measured productivity of each production well is the first tested productivity of each production well. In practical applications, the first test productivity of each production well can be obtained by user input, can be sent by other equipment, and can also be obtained by analyzing the well test data of the production well by the terminal. When the specified bottom hole flowing pressure is atmospheric pressure, the terminal can determine the corresponding productivity of each production well in the multiple production wells as the first test productivity when the bottom hole flowing pressure is atmospheric pressure.

Step 203: and acquiring an attribute value corresponding to each seismic attribute in the plurality of seismic attributes of each production well in the plurality of production wells at a position point corresponding to the target reservoir.

It should be noted that, because the target reservoir is composed of a plurality of location points, and each production well in the plurality of production wells is distributed on the target reservoir in the form of a point, each production well in the plurality of production wells corresponds to a location point in the target reservoir, and after obtaining the attribute value corresponding to each seismic attribute in the plurality of seismic attributes at each location point in the plurality of location points of the target reservoir of the target hydrocarbon block, the location point corresponding to each production well in the target reservoir can be determined according to the location of each production well in the plurality of production wells in the target hydrocarbon block, so as to obtain the attribute value corresponding to each seismic attribute in the plurality of seismic attributes of each production well at the location point corresponding to the target reservoir from the obtained attribute values of the target reservoir.

Step 204: determining an influence coefficient of each seismic attribute of the plurality of seismic attributes on the test productivity based on the first test productivity of each production well of the plurality of production wells and the attribute value of each seismic attribute of the plurality of seismic attributes corresponding to each production well of the plurality of production wells.

It should be noted that each of the multiple seismic attributes represents an original geological feature of the target reservoir, however, in a case where multiple production wells have been deployed in the target hydrocarbon block, the geological feature of the target reservoir may change, and therefore, merely fusing the multiple seismic attributes that can represent the original geological feature of the target reservoir may not accurately reflect the change in the geological feature of the target reservoir after the multiple production wells have been deployed. Based on this, in the embodiment of the present invention, before the terminal fuses the plurality of seismic attributes, an influence coefficient of each of the plurality of seismic attributes on the test productivity may be determined based on the first test productivity of each of the plurality of production wells and the attribute value of each of the plurality of seismic attributes corresponding to each of the plurality of production wells, the fusion weight may be determined according to the influence coefficient of each of the plurality of seismic attributes on the test productivity, and the attribute value of each of the plurality of seismic attributes may be fused according to the fusion weight. Therefore, the fusion weight reflects the influence of the current seismic attribute on the productivity of the production well, namely reflects the influence of the current geological characteristics on the productivity of the production well, so that the fusion result can better accord with the current geological characteristics of the target reservoir by fusing the attribute values of the seismic attributes with the fusion weight.

For any seismic attribute A in the plurality of seismic attributes corresponding to each production well in the plurality of production wells, determining an influence coefficient of the seismic attribute A on the test productivity through the following formula (1) based on the first test productivity of each production well in the plurality of production wells and the attribute value of the seismic attribute A corresponding to each production well in the plurality of production wells;

wherein r is the influence coefficient of the seismic attribute A on the test productivity, x_iThe seismic property A property value corresponding to the ith production well in the plurality of production wells is referred to, yi is the first tested capacity of the ith production well in the plurality of production wells, and n is the number of the plurality of production wells.

Taking 10 production wells in a target hydrocarbon block as an example, table 2 shows the property value of the seismic property, which is the average instantaneous frequency of the seismic properties of a plurality of seismic properties corresponding to each of the 10 production wells, and the first test productivity of the production well. Referring to table 2, the first column of table 2 shows the production well number for each of the 10 production wells, the second column shows the attribute value for the seismic attribute, the average instantaneous frequency for each of the 10 production wells, and the third column shows the first test yield value for each of the 10 production wells.

TABLE 2

Number of well	Average instantaneous frequency	First test productivity (Wanfang/Tian)
			Well 1	0.503	7.273
Well 2	0.922	2.424
			Well 3	0.859	33.939
Well 4	1.090	46.061
			Well 5	2.473	33.939
Well 6	2.620	7.273
			Well 7	2.766	7.273
Well 8	3.416	60.606
			Well 9	4.883	60.606
Well 10	5.952	191.515

Based on the property value of the average instantaneous frequency of each production well in the 10 production wells in the target hydrocarbon zone block and the first test productivity of the production well corresponding to each production well shown in table 2, the influence coefficient of the seismic property of the average instantaneous frequency in the target hydrocarbon zone block on the first test productivity is determined to be 0.587 through the formula (1). It should be noted that the attribute value of the average instantaneous frequency corresponding to each production well and the first test capacity of each production well shown in table 2 are exemplary data given by the embodiment of the present invention, and do not constitute a limitation on the attribute value of the average instantaneous frequency and the first test capacity.

For each seismic attribute in the plurality of seismic attributes, the influence coefficient of the corresponding seismic attribute on the test productivity is determined through the formula (1) by referring to the method for determining the influence coefficient of the average instantaneous frequency on the test productivity, so that the influence coefficient of each seismic attribute in the plurality of seismic attributes on the test productivity is obtained.

Step 205: determining a fusion weight for each of the plurality of seismic attributes based on an impact coefficient of each of the plurality of seismic attributes on the test productivity.

In the embodiment of the invention, the fusion weight of each seismic attribute in the plurality of seismic attributes can be determined based on the influence coefficient of each seismic attribute in the plurality of seismic attributes on the test productivity in the following two ways.

The first mode is as follows: the terminal can calculate the sum of the multiple influence coefficients, determine the ratio of the influence coefficient of each seismic attribute to the test productivity in the multiple influence coefficients according to the influence coefficient of each seismic attribute to the test productivity in the multiple seismic attributes and the sum of the multiple influence coefficients, and determine the ratio of the influence coefficient of each seismic attribute to the test productivity in the multiple seismic attributes to the sum of the influence coefficients as the fusion weight of each seismic attribute in the multiple seismic attributes.

The second mode is as follows: acquiring N influence coefficients from the plurality of determined influence coefficients, wherein each influence coefficient in the N influence coefficients is larger than other influence coefficients except the N influence coefficients in the plurality of influence coefficients; determining the fusion weight of the seismic attribute corresponding to each influence coefficient in the N influence coefficients according to the size of the N influence coefficients to obtain N fusion weights corresponding to the N seismic attributes, wherein the N influence coefficients and the N fusion weights are in positive correlation; and determining the fusion weight of the seismic attribute corresponding to each influence coefficient in the other influence coefficients except the N influence coefficients in the plurality of influence coefficients as a first numerical value.

It should be noted that, because the calculation amount for determining the fusion weight of each seismic attribute in the plurality of seismic attributes is large and the process is complex, N influence coefficients can be selected from the plurality of influence coefficients, and each influence coefficient in the N influence coefficients is larger than other influence coefficients except the N influence coefficients in the plurality of influence coefficients, that is, the N influence coefficients with a larger influence coefficient on the test productivity by each seismic attribute in the plurality of seismic attributes are selected, so as to reduce the calculation amount for determining the fusion weight of each seismic attribute in the plurality of seismic attributes and improve the calculation efficiency.

For example, the terminal may rank the plurality of influence coefficients in a descending order or a descending order to obtain a ranking result, and obtain N influence coefficients from the ranking result. If the sorting result is a sorting result in which a plurality of influence coefficients are arranged from large to small, the first N influence coefficients may be obtained from the sorting result. If the sorting result is obtained according to the sorting from small to large, the last N influence coefficients can be obtained from the sorting result. Wherein N is less than the number of the influence coefficients in the sorting result, and N is a positive integer greater than 1.

After acquiring the N influence coefficients, the terminal may determine the fusion weight of the seismic attribute corresponding to each influence coefficient in the N influence coefficients by using the following formula (2).

Wherein N is the number of the acquired influence coefficients, k_iRefers to the fusion weight r of the seismic attribute corresponding to the ith influence coefficient in the N influence coefficients_iRefers to the ith influence coefficient in the N influence coefficients, wherein i is a positive integer which is greater than 1 and less than or equal to N.

For example, table 3 shows the attribute names and influence coefficients of a plurality of seismic attributes, where the first column of table 3 is the attribute names of the plurality of seismic attributes, the second column is the influence coefficients corresponding to the plurality of seismic attributes, and the third column is the ranking from large to small.

TABLE 3

Attribute name	Coefficient of influence	Rank order
			Root mean square amplitude	0.174	11
Average peak amplitude	0.240	10
			Mean valley amplitude	0.330	7
Maximum peak amplitude	0.579	3
			Analyzing the maximum peak amplitude value in the time window	0.370	6
Maximum valley amplitude	0.271	9
			Average instantaneous frequency	0.587	2
Instantaneous phase	0.615	1
			Length of wave form	0.517	5
Number of peaks	0.274	8
			Trough of wave	0.540	4

As can be seen from table 3, the 11 seismic attribute influence coefficients are arranged from large to small, and the obtained ranking results include an instantaneous phase influence coefficient, an average instantaneous frequency influence coefficient, a maximum peak amplitude influence coefficient, a trough number influence coefficient, a waveform length influence coefficient, a maximum peak amplitude influence coefficient in the analysis time window, an average trough amplitude influence coefficient, a crest number influence coefficient, a maximum trough amplitude influence coefficient, an average peak amplitude influence coefficient, and a root-mean-square amplitude influence coefficient. Assuming that N is 4, in this case, the terminal may obtain, from the sorting result, the first 4 influence coefficients, which are the influence coefficient of the instantaneous phase 0.615, the influence coefficient of the average instantaneous frequency 0.587, the influence coefficient of the maximum peak amplitude 0.579, and the influence coefficient of the number of valleys 0.540, respectively. Determining the fusion weight of the seismic attribute corresponding to each influence coefficient in the first 4 influence coefficients through the formula (2), wherein the obtained fusion weight of the instantaneous phase is 0.2650, the fusion weight of the average instantaneous frequency is 0.2529, the fusion weight of the maximum peak amplitude is 0.2495, and the fusion weight of the trough number is 0.2326.

It should be noted that, after determining the fusion weight of the seismic attribute corresponding to each influence coefficient of the N influence coefficients, the fusion weight of the seismic attribute corresponding to each of the influence coefficients other than the N influence coefficients in the plurality of influence coefficients may also be determined as a first numerical value, specifically, the first numerical value may be 0, that is, the fusion weight of the seismic attribute corresponding to each of the influence coefficients other than the N influence coefficients in the plurality of influence coefficients may be set to 0, in other words, by setting the fusion weight of the seismic attribute corresponding to each of the other influence coefficients than the N influence coefficients among the plurality of influence coefficients to 0, when the plurality of seismic attributes are fused, the fusion result does not contain the influence of the attribute value of the seismic attribute corresponding to each influence coefficient in other influence coefficients except the N influence coefficients in the plurality of influence coefficients.

Step 206: and fusing the plurality of attribute values on each position point according to the fusion weight of each seismic attribute to obtain a seismic attribute fusion result of the target reservoir.

Specifically, the terminal may fuse the multiple attribute values at each location point according to steps 2061 and 2062 to obtain a seismic attribute fusion result of the target reservoir.

Step 2061: for any position point B in a plurality of position points in the target storage layer, fusing the plurality of attribute values through the following formula (3) based on the fusion weight of each seismic attribute in the plurality of seismic attributes and the attribute value corresponding to each seismic attribute in the plurality of seismic attributes on the position point B to obtain a fusion result on the position point B in the target storage layer;

In the embodiment of the invention, the multiple seismic attributes of any one position point a in multiple position points in the target reservoir can be fused in the following two ways.

The first mode is as follows: and fusing the plurality of seismic attributes of any position point B in the plurality of position points in the target reservoir according to a formula (3) based on the fusion weight of each seismic attribute in the plurality of seismic attributes and the attribute value corresponding to each seismic attribute in the plurality of seismic attributes on the position point B.

For example, assume that the seismic attributes are instantaneous phase, average instantaneous frequency, maximum peak amplitude, and trough number, respectively, where for any one position point B of the plurality of position points in the target reservoir, the fusion weight of the instantaneous phase at the position point is 0.2650, the attribute value of the instantaneous phase is 410, the fusion weight of the average instantaneous frequency is 0.2529, the attribute value of the average instantaneous frequency is 270, the fusion weight of the maximum peak amplitude is 0.2495, the attribute value of the maximum peak amplitude is 310, the fusion weight of the trough number is 0.2326, and the attribute value of the trough number is 380. And fusing the plurality of seismic attributes of any position point B in the plurality of position points in the target reservoir according to the formula (3) based on the fusion weight of each seismic attribute in the plurality of seismic attributes and the attribute value corresponding to each seismic attribute in the plurality of seismic attributes on the position point B, so as to obtain a fusion result 342.666 of the position point B.

The second mode is as follows: normalizing the attribute value corresponding to each of the plurality of seismic attributes on the position point B, and fusing the plurality of seismic attributes of any position point B in the plurality of position points in the target storage layer according to a formula (3) based on the fusion weight of each of the plurality of seismic attributes and the normalized value of the attribute value corresponding to each of the plurality of seismic attributes on the position point B.

It should be noted that, because the ranges of the attribute values corresponding to each of the seismic attributes are different, wherein the attribute values of some seismic attributes may not even be in an order of magnitude, in this case, if the attribute values are directly fused according to the fusion weight of each of the seismic attributes, for the attribute values that are too large or too small, the finally obtained fusion result will not truly reflect the influence of the attribute values, that is, the accuracy of the fusion result will be influenced. And then fusing the plurality of seismic attributes of the position point B according to a formula (3) based on the fusion weight of each seismic attribute in the plurality of seismic attributes and the normalized attribute value corresponding to each seismic attribute in the plurality of seismic attributes.

Specifically, when the attribute value corresponding to each seismic attribute in the plurality of seismic attributes is normalized, for each seismic attribute in the plurality of seismic attributes, an attribute value corresponding to the corresponding seismic attribute at each position point in a plurality of position points of a target reservoir of a target hydrocarbon block may be obtained, a maximum attribute value of the corresponding seismic attribute may be determined from the obtained attribute values, and a ratio between the attribute value corresponding to the corresponding seismic attribute at the position point B and the maximum attribute value may be determined as a normalized attribute value corresponding to the corresponding seismic attribute at the position point B.

For example, Table 4 shows the maximum attribute value for each of the plurality of seismic attributes within the target reservoir and the attribute value for each of the plurality of seismic attributes at location point B. Wherein the first column shows attribute names of the plurality of seismic attributes, the second column shows attribute values of each of the plurality of seismic attributes at location point B, the third column shows maximum attribute values of each of the plurality of seismic attributes within the target reservoir, the fourth column shows corresponding normalized attribute values of each of the plurality of seismic attributes at location point B, and the fifth column shows fusion weights of each of the plurality of seismic attributes at location point B.

TABLE 4

Seismic attribute	Attribute value	Maximum attribute value	Normalizing attribute values	Fusion weights
					Instantaneous phase	410	500	0.82	0.2650
Average instantaneous frequency	270	450	0.60	0.2529
					Maximum peak amplitude	310	600	0.52	0.2495
Number of wave trough	380	550	0.69	0.2326

The normalized attribute values and fusion weights corresponding to 4 seismic attributes in any one of the plurality of location points B in the target reservoir shown in table 4 are fused by equation (3), and the fusion result of the location point B is obtained as 0.6593.

It should be noted that the terminal may determine the fusion result of each of the plurality of location points of the target reservoir according to the method for determining the fusion result of the location point B described above, and then the terminal may generate the seismic attribute fusion result of the target reservoir based on the fusion result of each of the plurality of location points of the target reservoir through the following step 2062.

Step 2062: and generating a seismic attribute fusion result of the target reservoir based on the determined fusion result on the plurality of position points in the target reservoir.

After determining the fusion result of each of the plurality of location points in the target storage layer, the terminal may obtain a numerical range of the fusion result according to a maximum value and a minimum value of the plurality of fusion results, then divide the numerical range into a plurality of numerical intervals, and set a corresponding chromatogram for each numerical interval. And then, the terminal can determine the color spectrum corresponding to each position point according to the numerical value interval to which the fusion result of each position point in the plurality of position points belongs, further generates the seismic attribute fusion diagram of the target reservoir according to the color spectrum corresponding to each position point, and can determine the seismic attribute fusion diagram as the seismic attribute fusion result of the target reservoir.

Of course, the above description is only an expression form of an exemplary seismic attribute fusion result given in the embodiment of the present invention, and does not constitute a limitation on the seismic attribute fusion result. For example, in one possible implementation, after determining the fusion result of each location point, a data set including the coordinates of each location point in the plurality of location points and the fusion result of each location point is output, and the data set may be the seismic attribute fusion result of the target reservoir. For another example, the terminal may further represent the fusion result of the plurality of location points in the target reservoir in a graph through contours or other representation forms, and at this time, the output image is the seismic attribute fusion result of the target reservoir.

In the embodiment of the invention, different fusion weights can be set for each seismic attribute in the plurality of seismic attributes, the plurality of seismic attributes are fused according to the fusion weight of each seismic attribute to obtain a fusion result, the distribution result of an oil and gas reservoir can be uniquely determined according to the obtained fusion result, the deployment well position of a new well can be uniquely determined according to the distribution result of the oil and gas reservoir, and the problem that the deployment well position of the new well is uncertain due to the distribution results of various oil and gas reservoirs in the related technology is solved. Moreover, the fusion weight of each seismic attribute represents the importance degree of the corresponding seismic attribute in the seismic attribute fusion process, so that the fusion result obtained by fusing the plurality of seismic attributes according to different fusion weights can more accurately reflect the geological features in the oil-gas zone, and therefore, when the distribution of the oil-gas reservoir is determined according to the fusion result, the accuracy of determining the distribution of the oil-gas reservoir can be improved, and the accuracy of determining the deployment well position of a new well can be further improved. In addition, when the plurality of seismic attributes are fused, each seismic attribute in the plurality of seismic attributes can be combined with the first test productivity of the plurality of production wells in the target block, the fusion weight of each seismic attribute in the plurality of seismic attributes is determined according to the influence coefficient of each seismic attribute in the plurality of seismic attributes and the first test productivity, and the plurality of seismic attributes are further fused according to the fusion weight of each seismic attribute, so that the obtained fusion result can reflect the geological characteristics of the target reservoir after the plurality of production wells are deployed more accurately, the distribution of the oil and gas reservoir determined according to the fusion result is more accurate, and the accuracy of the determined well position for deploying the new well is further improved.
