Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Considering the problem that some target work areas lack three-dimensional geological exploration conditions due to the influence of input cost or other objective factors, only two-dimensional seismic data exist, and the prior art cannot be used for analyzing three-dimensional geological characteristics, so that the geological exploration efficiency and the recognition rate of the target work areas are low, the application provides a seismic data processing method and a seismic data processing device, by obtaining the initial position coordinates of each sampling point on each two-dimensional measuring line in the existing two-dimensional seismic data of the target work areas, selecting an initial two-dimensional measuring line, determining the line distance, the track distance and the line inclination angle of the three-dimensional measuring net to be constructed according to the relative position relation between the sampling points on the initial two-dimensional measuring line, then assigning values to the corresponding initial sampling points in the constructed three-dimensional measuring net according to the initial position coordinates of the initial sampling points on the initial two-dimensional measuring line, and accordingly determining the corresponding target position coordinates of the sampling points on the two-dimensional measuring line in the three-dimensional measuring, and then obtain corresponding three-dimensional seismic data and three-dimensional seismic data body, and carry out geological feature analysis to the target work area according to this three-dimensional seismic data body, obtain corresponding geological interpretation result, this application constructs corresponding three-dimensional survey net according to existing two-dimensional survey line characteristic, and carry out position coordinate transformation to known each sampling point, from this under the condition that only two-dimensional seismic data is available, also can be convenient, the accurate three-dimensional seismic data body that obtains, and carry out geological feature analysis to the target work area with this, promoted geological exploration work efficiency.

In order to conveniently and effectively perform three-dimensional geological analysis on existing two-dimensional seismic data and further improve the geological exploration efficiency of a target work area, the application provides an embodiment of a seismic data processing method, and referring to fig. 1, the seismic data processing method specifically comprises the following contents:

step S101: and acquiring initial position coordinates of each sampling point on each two-dimensional measuring line in the two-dimensional seismic data of the target work area.

It can be understood that whether two-dimensional seismic data or three-dimensional seismic data are obtained, the data can be finally stored in the SEGY format, and the 240-byte track header information of the SEGY format data contains several important parameters: 1. the serial number of the seismic record (typically the head position 1); 2. a common center point (CDP) number (typically the curb location 21); 3. the group number of the two-dimensional seismic record (which can also be understood as the identification row number of the two-dimensional survey line, generally the head position 9); 4. the abscissa X of the sample point on the two-dimensional profile (typically the toe position 73); 5. the ordinate Y of the sample point on the two-dimensional line (typically the toe position 77); 6. line (Line) number (generally, track head position 189; 7; Trace number of seismic record (generally, track head position 193), 8, abscissa X (generally, track head position 181) of a sampling point on a three-dimensional Line, and 9 ordinate Y (generally, track head position 185) of the sampling point on the three-dimensional Line.

It can be understood that the position coordinates of each sampling point on the three-dimensional survey line are absent in the two-dimensional seismic data acquired in the target work area, so that it is difficult to further generate a three-dimensional seismic data volume.

Step S102: and determining the line distance, the track distance and the measuring line inclination angle of the three-dimensional measuring net according to the initial position coordinates of the sampling points on the initial two-dimensional measuring line.

It can be understood that, in a target work area, the setting position of each two-dimensional survey line is generally determined based on the actual operation condition on site, each two-dimensional survey line does not always have the same length, the initial sampling point is not on a straight line, some two-dimensional survey lines can also be bent when extending according to the difference of the actual operation environment, the position setting of the two-dimensional survey lines is obviously different from the position setting of the three-dimensional survey lines in the three-dimensional survey network, and therefore the seismic data acquired by each sampling point on the two-dimensional survey lines can form a three-dimensional seismic data body.

Optionally, a part of two-dimensional survey lines are selected in advance as a processing batch, and one of the two-dimensional survey lines is selected as an initial two-dimensional survey line of the processing batch, wherein the selection rule of the initial two-dimensional survey line can determine the line distance, the track distance and the survey line inclination angle of a virtual three-dimensional survey net to be constructed according to the relative distance and the relative angle of the initial position coordinates between sampling points on the initial two-dimensional survey line based on the data definition, the survey line length and the survey line flatness.

Alternatively, from the initial position coordinates (10,10) of the initial sampling point on the initial two-dimensional line and the initial position coordinates (20,20) of the sampling point adjacent to the initial sampling point on the initial two-dimensional line, the relative distance (i.e., track pitch) and relative angle between the two initial position coordinates can be known, the relative distance can be set as the track pitch of the three-dimensional geodesic, and further the line pitch of the three-dimensional geodesic (line pitch is equal to track pitch) can be determined, and the relative angle can also be set as the inclination angle (e.g., 45 degrees) of the three-dimensional geodesic.

Step S103: and determining the corresponding target position coordinates of each sampling point in the three-dimensional measuring network according to the line distance, the track distance and the measuring line inclination angle of the three-dimensional measuring network and the initial position coordinates of the initial sampling point on the initial two-dimensional measuring line.

It can be understood that the setting position of each three-dimensional survey line in the three-dimensional survey network can be constructed and obtained according to the line distance, the track distance and the survey line inclination angle of the three-dimensional survey network, but at the moment, the target position coordinates of each sampling point on each three-dimensional survey line are not limited.

Alternatively, the initial position coordinates of the initial sampling point on the initial two-dimensional line may be set as the target position coordinates of the initial sampling point on the initial three-dimensional line in the three-dimensional network, for example, if the initial position coordinates of the initial sampling point on the initial two-dimensional line are (10,10), it is known that the target position coordinates of the initial sampling point on the initial three-dimensional line are also (10, 10).

It can be understood that, because a three-dimensional measurement network is constructed and the target position coordinates of the initial sampling points on the initial three-dimensional measurement lines are known, the target position coordinates of the sampling points on each three-dimensional measurement network in the three-dimensional measurement network can be obtained according to the setting characteristics of the three-dimensional measurement network (the line distance is equal to the track distance, the three-dimensional measurement lines are parallel and equal in length, and the revealing sampling points of the three-dimensional measurement lines are on the same straight line).

It will be appreciated that the line and track numbers in the two-dimensional grid formed by the processing batch are in one-to-one correspondence with the line and track numbers in the three-dimensional grid.

Step S104: and obtaining a three-dimensional seismic data volume of the target work area according to the seismic data in the two-dimensional seismic data corresponding to the target position coordinates of each sampling point in the three-dimensional measuring network.

Step S105: and analyzing geological characteristics of the three-dimensional seismic data volume to obtain a geological interpretation result.

It can be understood that, from the above description, it is known that the target position coordinates corresponding to each sampling point in the existing two-dimensional seismic data in the constructed three-dimensional survey network are set as the abscissa X and the ordinate Y of the sampling point on the three-dimensional survey line corresponding to the SEGY-format data, that is, the header data of the header positions 181 and 185 in the SEGY-format data are respectively filled, so that the three-dimensional seismic data (SEGY-format storage) completed by the target work area can be obtained, an accurate three-dimensional seismic data body can be smoothly obtained according to the three-dimensional seismic data body, and the target work area is subjected to targeted geological characteristic analysis (for example, lithology prediction) according to the three-dimensional seismic data body, so as to obtain the corresponding geological interpretation result (for example, lithology prediction result of the target work area).

As can be seen from the above description, the seismic data processing method provided in the embodiment of the present application can determine the line distance, the track distance, and the line inclination of the three-dimensional measurement network to be constructed by obtaining the initial position coordinates of each sampling point on each two-dimensional measurement line in the existing two-dimensional seismic data of the target work area, selecting an initial two-dimensional measurement line, and according to the relative position relationship between the sampling points on the initial two-dimensional measurement line, then assigning values to the corresponding initial sampling points in the constructed three-dimensional measurement network according to the initial position coordinates of the initial sampling points on the initial two-dimensional measurement line, thereby determining the corresponding target position coordinates of each sampling point on the two-dimensional measurement line in the three-dimensional measurement network, and further obtaining the corresponding three-dimensional seismic data and three-dimensional seismic data volume, and performing geological characteristic analysis on the target work area according to the three-dimensional seismic data volume, so as to obtain the corresponding geological interpretation result, according to the method, the corresponding three-dimensional measuring network is constructed according to the existing two-dimensional measuring line characteristics, position coordinate transformation is carried out on known sampling points, therefore, under the condition that only two-dimensional seismic data exist, the corresponding three-dimensional seismic data can be conveniently and accurately obtained, geological characteristic analysis is carried out on a target work area according to the three-dimensional seismic data, and the geological exploration working efficiency is improved.

In order to determine the layout characteristics of the three-dimensional survey network, in an embodiment of the seismic data processing method of the present application, the following is further included: determining the line distance, the track distance and the line measuring inclination angle of the three-dimensional measuring net according to the distance between the initial position coordinates of a first sampling point and a second sampling point adjacent to the first sampling point on the initial two-dimensional measuring line and the direction of a connecting line formed by the first sampling point and the second sampling point, wherein the first sampling point is the initial sampling point on the initial two-dimensional measuring line, and the line distance is equal to the track distance.

For example, from the initial position coordinates (10,10) of the initial sampling point (i.e., the first sampling point) on the initial two-dimensional line and the initial position coordinates (20,20) of the sampling point (i.e., the second sampling point) adjacent to the initial sampling point on the initial two-dimensional line, the relative distance (i.e., the track pitch) and the relative angle between the two initial position coordinates can be known, the relative distance can be set as the track pitch of the three-dimensional geodesic, the line pitch of the three-dimensional geodesic can be further determined (the line pitch is equal to the track pitch), and the relative angle can be set as the line inclination (e.g., 45 degrees) of the three-dimensional geodesic.

In order to accurately obtain the target position coordinates of each sampling point in the three-dimensional measurement network, in an embodiment of the seismic data processing method of the present application, referring to fig. 2, the following contents are further specifically included:

step S201: and determining the target position coordinates of the initial sampling points on the initial three-dimensional measuring lines in the three-dimensional measuring network according to the initial position coordinates of the initial sampling points on the initial two-dimensional measuring lines.

Step S202: and determining the corresponding target position coordinates of each sampling point in the three-dimensional measuring network according to the target position coordinates of the initial sampling point on the initial three-dimensional measuring line in the three-dimensional measuring network, and the track distance, the line distance and the measuring line inclination angle of the three-dimensional measuring network.

In order to further accurately obtain the target position coordinates of each sampling point in the three-dimensional measuring network, in an embodiment of the seismic data processing method of the present application, referring to fig. 3, the following contents are also specifically included:

step S301: and determining the corresponding target position coordinates of other sampling points on the initial two-dimensional measuring line except the initial sampling point on the initial three-dimensional measuring line according to the target position coordinates of the initial sampling point on the initial three-dimensional measuring line in the three-dimensional measuring network, the track pitch and the measuring line inclination angle of the three-dimensional measuring network.

For example, it is known from the above description that the target position coordinates of the initial sampling point on the initial three-dimensional measuring line are (10,10), the track pitch of the three-dimensional measuring net is 10, and the inclination angle of the measuring line of the three-dimensional measuring net is 45 degrees, then the target position coordinates of each sampling point on the initial three-dimensional measuring line can be sequentially calculated according to the trigonometric function calculation rule, wherein each sampling point on the initial three-dimensional measuring line corresponds to each sampling point on the initial two-dimensional measuring line one-to-one, and only the position coordinates are different.

Step S302: and determining the target position coordinates of the initial sampling points of other two-dimensional measuring lines except the initial two-dimensional measuring line on other three-dimensional measuring lines except the initial three-dimensional measuring line in the three-dimensional measuring network according to the target position coordinates of the initial sampling points on the initial three-dimensional measuring line and the line distance and the measuring line inclination angle of the three-dimensional measuring network.

For example, it is known from the above description that the target position coordinates of the initial sampling points on the initial three-dimensional measuring lines are (10,10), the line distances of the three-dimensional measuring network are 10 (the line distances are equal to the track distances), the inclination angles of the three-dimensional measuring lines are 40 degrees, and the initial sampling points of the three-dimensional measuring lines are located on the same straight line, then the target position coordinates of the initial sampling points of the three-dimensional measuring lines can be sequentially calculated according to the trigonometric function calculation rule, wherein the initial sampling points of the three-dimensional measuring lines correspond to the sampling points of the two-dimensional measuring lines one to one, and only the position coordinates are different.

Step S303: and determining the target position coordinates of other sampling points on other two-dimensional measuring lines except the initial sampling point on other three-dimensional measuring lines except the initial three-dimensional measuring line according to the target position coordinates of the initial sampling point of each three-dimensional measuring line in the three-dimensional measuring network, the track pitch and the measuring line inclination angle of the three-dimensional measuring network.

For example, if the target position coordinates of the start sampling points of the three-dimensional measuring lines are known from the above description, the track pitch of the three-dimensional measuring network is 10, and the inclination angle of the three-dimensional measuring network is 45 degrees, the target position coordinates of the sampling points on the three-dimensional measuring lines can be sequentially calculated according to the trigonometric function calculation rule, wherein the sampling points on the three-dimensional measuring lines correspond to the sampling points on the two-dimensional measuring lines one to one, and only the position coordinates are different.

In order to make the obtained three-dimensional seismic data volume clearer, in an embodiment of the seismic data processing method of the present application, referring to fig. 4, the following contents are further included:

step S401: and copying each three-dimensional measuring line in the three-dimensional measuring net at least once.
