Technical Field

The invention relates to a drilling machine in the field of petroleum drilling, in particular to a modular petroleum drilling machine.

Background

The disassembly and assembly workload of the tower derrick is large, and a professional team and a special machine are needed, so that high-altitude operation is needed, and the safety is low; some derricks take root on the drilling platform surface and have poor stability. The traditional K-type derrick adopts a winch large rope to lift and place the derrick, and a special lifting large rope needs to be matched with the winch large rope; in the process of lifting and placing the derrick of the petroleum drilling machine, because operators misjudge and misoperate, the collapse accident of the derrick easily occurs, and four derricks of the derrick are scrapped; the derrick lifting or lowering process has the problems of over-high lifting or lowering speed, short manual operation reaction time, unstable lifting and lowering, asynchronous buffer cylinder and improper matching of the buffer cylinder and a winch, and is easy to cause danger. In addition, the racking platform, the travelling hoisting system and the large rope must be firstly dismounted and the large rope must be pulled out during the transportation of the derrick, and the travelling hoisting system and the large rope are transported separately, so that the problems that the workload of dismounting and mounting the derrick when the drilling machine is moved is large and the number of transportation vehicles is large are caused.

Disclosure of Invention

The modular petroleum drilling machine overcomes the defects of the prior art, the derrick is rooted on the base, the large rope and the travelling and hoisting system are integrally transported along with the derrick, the workload of disassembly and assembly is reduced, the derrick shipping vehicles are reduced, the derrick and a drill floor are lifted and placed without using a winch, the large rope and a special lifting large rope, the derrick and the drill floor are driven by a hydraulic cylinder, and the lifting and placing processes are stable.

In order to solve the technical problems, the invention is realized by adopting the following technical scheme:

a modular petroleum drilling rig comprising a derrick, a drill floor, a pedestal, a winch, a support arm, a derrick base, a rope, a crown block and a racking platform, wherein: the derrick, the drill floor and the base are all independent modular structures; the base is hinged with the drill floor through a support arm, a base hydraulic cylinder is arranged between the base and the drill floor, and the drill floor is lifted and stacked along with the extension of the base hydraulic cylinder; the racking platform is fixedly connected with the derrick; the winch is fixed on the base; a dead rope winch is arranged on a back cross beam of the derrick, a large rope is connected to the winch, and one end of the large rope penetrates through the crown block and then is directly wound on the dead rope winch; the derrick comprises a derrick base, a derrick hydraulic cylinder, a hinge shaft, a derrick base and a derrick hydraulic cylinder, wherein the derrick base is hinged to the derrick base fixed on the base through the hinge shaft, the derrick hydraulic cylinder is installed between the derrick and the base, and the derrick extends and retracts to stand and lay flat around the hinge shaft on one side.

The above scheme further comprises:

the derrick is of a multi-section telescopic structure.

The derrick is a three-section telescopic structure, the three sections of derricks are sequentially spliced and matched, and two adjacent derricks are telescopic and locked by matching the hydraulic cylinders with the locking blocks.

The derrick hydraulic cylinder is a multi-stage hydraulic cylinder.

The derrick comprises two hydraulic cylinders which are arranged on the same side of the derrick.

The base hydraulic cylinder and the supporting arm are multiple in number.

The base hydraulic cylinder is connected between the base and the drill floor, and the lifting and the descending of the drill floor are realized by two base hydraulic cylinders. After the push rod of the base hydraulic cylinder extends out, the drill floor rises, and after the base hydraulic cylinder retracts, the drill floor falls back to the base.

Two groups of derrick bases are fixed on the base, when the derrick is laid down, one group of feet of the derrick is hinged with one derrick base, and after the derrick is completely lifted and erected, the other group of suspended feet of the derrick is fixedly connected with the other group of derrick bases. The derrick is of a three-section telescopic structure, and the three-section derrick is integrally moved together with the racking platform, the travelling and hoisting system and the large rope after being retracted without being disassembled and respectively loaded. The derrick is lifted and lowered by adopting a front-falling structure, the derrick is lifted and lowered by a derrick hydraulic cylinder, the derrick hydraulic cylinder is a three-stage hydraulic cylinder, and the hydraulic cylinder and the push rod are respectively hinged with the base and the derrick.

The derrick roots on the base, and the stability is better than that of the derrick which roots on the drilling platform surface. When the crane is moved, the crane does not pull out the large rope, the large rope only needs to be pulled out from the winch and then wound on the dead rope winch, and the dead rope winch is arranged on the back cross beam of the derrick, so that the large rope and the travelling crane system are transported integrally along with the derrick.

A derrick lifting process: at the beginning, the base is moved to the position of a wellhead, and the derrick and the drill floor are in a laying state; firstly, a derrick is lifted to an upright state by a derrick hydraulic cylinder, and a suspension foot of the derrick is fixed on a derrick base; then, after the drill floor is lifted by the base hydraulic cylinder, the four supporting arms are in an upright state and locked; then, the second-stage derrick and the third-stage derrick which are contracted in the derrick are sequentially ejected out by the hydraulic cylinder to complete the extension of the whole derrick; finally, the large rope is detached from the dead rope winch of the derrick back beam and is loaded into the winch. The sequence of the derrick laying process and the derrick lifting process is opposite.
