AI Technical Summary

Technical Problem

Existing drilling equipment is ill-suited for shallow waters and complex terrains such as swamps, lakes, and rivers, making it difficult to move quickly and operate efficiently, thus limiting the exploration and development of oil and gas resources.

Method used

A shallow-water mobile drilling platform system was designed, which adopts a modular structure including a floating body module, a support module, a drilling rig substructure module, and a derrick system. Combined with a ballast water tank and a double-layer sliding device, it enables the platform to be quickly towed, set on the bottom, and efficiently drill in multiple well locations.

Benefits of technology

It enables rapid movement and efficient operation in shallow water environments, reduces transfer cycles, improves drilling efficiency, overcomes transportation limitations in complex terrain, and provides stability and living support.

Abstract

The application discloses a shallow-water movable drilling platform system, which comprises a floating body module, a support module and a drilling machine lower module. The floating body module is located at the lowermost part of the system, and is internally provided with a plurality of groups of ballast tanks and is provided with a U-shaped notch at the end. The support module is installed above the floating body module. The upper part of the support module is provided with the drilling machine lower module, a bulk material processing module and a drilling auxiliary module. The bulk material processing module is located between the drilling machine lower module and the drilling auxiliary module. The upper part of the drilling machine lower module is provided with a derrick system. The upper part of the drilling auxiliary module is sequentially provided with a living module and a helicopter deck. The system is moved by the whole towing mode, and does not need to disassemble and assemble the equipment. The derrick system can realize multi-well position operation without moving the platform through the up-down sliding device. The system is suitable for shallow water areas such as rivers and lakes, and has high operation efficiency and strong adaptability.
