Description

Technical Field

[0002] Core samples are roughly cylindrical underground material test blocks taken out from underground for testing using special drilling rigs. During the exploration and development of oil and gas fields, coring tools are lowered into the well according to the stratigraphic positions and designed depths obtained from the survey, and rock samples are drilled out. Cores are the most intuitive and practical data for understanding underground oil strata and the characteristics of the fluids they contain.

[0003] When sampling the core, since the sampled core may be deeper, a sampling connecting rod is usually added when drilling the core. When connecting the sampling connecting rod, it is necessary to fix the bottom connecting rod and then add another connecting rod to connect it. The bottom connecting rod is usually fixed manually, which is not secure. Once it cannot be fixed, it will fall and it will be inconvenient to salvage it, which is very inconvenient to operate. For this reason, we propose a core sampling device to solve the above problems. Summary of the invention
