Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas drilling, in particular to a pipe tool execution assembly and a drilling table robot. Background Art

[0002] In the process of oil and gas drilling, pipe tooling is a common and very important drilling equipment. Pipe tooling includes lifting nipples and conversion joints. The lifting nipples are special tools used to lift and lower shoulderless pipes (drill collars, power drills, tools, etc.). One end of this shoulderless pipe is an interface and the other end is a joint. During use, there is no need for traditional couplings to connect pipes. The structure is simpler and easy to process and manufacture. However, since there is no coupling, the hydraulic elevator cannot clamp the shoulderless pipe. Therefore, the lifting nipples are buckled with one end of the shoulderless pipe to meet the needs of on-site operations. The conversion joint is used for conversion connections between pipes of different sizes, and it also needs to be buckled with the end of the pipe.

[0003] At present, although the operations in the oil and gas drilling industry are rapidly developing towards mechanization and automation, the installation and disassembly of the drilling tool lifting pup joints and conversion joints on the drilling floor are mainly done manually, and the screw-in operations are mainly done with hydraulic and gas tongs. The degree of mechanization is low, the safety risks are high, and the operation efficiency is low.

[0004] Therefore, there is an urgent need for a pipe tooling execution assembly and a drilling table robot with high safety and high operating efficiency. Utility Model Content
