[0036] The substructure of a petroleum drilling rig is used to install the derrick, drawworks, rotary table, place drill pipes, wellhead tools, etc., and provide the installation space for the wellhead device and the operation platform for drilling operations. With the increasing drilling depth of the petroleum drilling rig, the setback load, rotary table load, and derrick load that the substructure needs to bear are also getting larger and larger. Therefore, higher requirements are put forward for the bearing capacity of the substructure. The substructure is designed to be more and more bulky, the structure is more and more complex, the weight is constantly increasing, and the transportation of the substructure is becoming more and more difficult.

[0037] After careful research by the applicant, it is found that the traditional drilling rig substructure has the following disadvantages:

[0038] ① The derrick is installed on the substructure, and the substructure needs to be designed very strong to support the weight of the derrick and the drilling load. Therefore, the traditional drilling rig substructure is heavy, has many components, is structurally complex, and has a high manufacturing cost;

[0039] ② In order to meet the requirements of road transportation, the traditional drilling rig substructure needs to be disassembled into multiple modules (≥4 vehicles) and reassembled after reaching the well site. This not only increases the transportation cost, but also takes a long time to assemble and disassemble the substructure, wasting a lot of manpower and material resources;

[0040] ③ The traditional drilling rig substructure generally adopts lifting methods such as using a drawworks to lift or a crane to hoist. Lifting with a drawworks is suitable for skid-mounted or truck-mounted drilling rigs equipped with a large-tonnage drawworks. Since an automated hydraulic drilling rig does not have a large-tonnage drawworks, the lifting method with a drawworks is not applicable to the substructure of an automated hydraulic drilling rig; if the crane hoisting method is adopted, a large-tonnage crane needs to be equipped, which additionally increases the hoisting cost;

[0041] ④ The substructure needs to be equipped with a track-type moving device for short-distance movement within the well site, which has a high cost.

[0042] The main purpose of the present utility model is to propose a hydraulic lifting substructure for a drilling rig to solve the problem of how to simplify the structure of the substructure for easy transportation.

The rig hydraulic lifting base 100 further includes a deck equipment 120, and the deck equipment 120 is detachably connected to the platform 11. Specifically, since the rig hydraulic lifting base 100 is independently provided from the derrick, the derrick and the rotary table directly transfer the drilling load to the ground instead of through the rig hydraulic lifting base 100. Therefore, the rig hydraulic lifting base 100 no longer needs to bear all the loads generated during drilling, and the rig hydraulic lifting base 100 can be designed as a non-load-bearing structure. This can reduce the weight of the rig hydraulic lifting base 100, reduce the material usage, thereby reducing the manufacturing cost. At the same time, it also simplifies the structural design of the rig hydraulic lifting base 100, making the manufacturing simpler. The rig hydraulic lifting base 100 only serves as the installation platform for the work platform 11 and the wellhead automation tools, and the operators can perform drilling operations more efficiently. The deck equipment 120 is installed and disassembled when the rig hydraulic lifting base 100 is in the low position. The first driving member 4 is used to drive the platform 11 and the deck equipment 120 to reciprocate between the lifting position 111 and the folding position 112. Compared with high-altitude operations, low-altitude operations are faster and more convenient, simplifying the installation and disassembly process, greatly shortening the time for disassembly, assembly and transportation, reducing the labor intensity of the operators, avoiding safety risks such as the fall of the operators and the dropping of equipment during high-altitude operations, and improving the operation safety. During transportation, the deck equipment 120 is removed, and the rig hydraulic lifting base 100 only needs to be split into two modules. One module includes the upper base 1, the lower base 2, the support column 3 and the first driving member 4, and the other module includes the deck equipment 120, the walking device 110, the hydraulic cathead device 8, the blowout preventer device 9 and the diagonal brace 7.

One end of the ladder 1203 is detachably connected to the balcony 1202, and the other end of the ladder 1203 abuts against the ground, so as to facilitate the movement of operators between the platform 11 and the ground. The inclination angle of the ladder 1203, the pedal spacing on the ladder 1203, etc. all meet the requirements of ergonomics. The pedals are designed with anti-slip features. The specific number of ladders 1203 can be selected according to actual needs, which is not limited in this embodiment; an escape exit is also provided on the balcony 1202, and the escape chute 1205 is located at the escape exit. One end of the escape chute 1205 is detachably connected to the balcony 1202, and the other end of the escape chute 1205 abuts against the ground, facilitating the movement of operators from the escape chute 1205 to the ground in case of an emergency; safety ropes 1206 are provided at both the safety exit and the escape exit. The two ends of the safety rope 1206 are respectively connected to the railings 1204 on both sides, further enhancing the safety of operators working at height and preventing operators from falling from the safety exit at night, causing safety accidents. Installation positions for equipment such as an iron roughneck and a tong tail post are reserved on the platform 11 to facilitate the expansion of the solution for the hydraulic lifting base 100 of the drilling rig.
