Description

technical field [0001] The invention relates to the technical field of drilling devices, in particular to a drilling device for natural gas geology and a drilling method thereof. Background technique [0002] After geological investigation and geophysical exploration, select the most favorable drilling position for oil and gas accumulation, and use drilling technology to drill through the oil and gas layers to test geophysical data, understand downhole oil and gas geological exploration data, calculate oil and gas reserves, and provide development prospects as follows: The purpose of drilling engineering, referred to as oil and gas drilling. The principles of oil and gas drilling and geological core drilling are basically the same. It’s just that oil and gas wells are relatively deep (generally more than 1,000 to 7,000 meters), large-caliber (generally opening 915 mm), and the final hole is 216 mm. Large-scale drilling rigs are used. Generally, the formation is recorded bas...

AI Technical Summary

Problems solved by technology

[0005] First: the installation of existing drill pipes requires rotation between the rotating rod and the rotating rod during assembly. The assembly is completed by driving the rotating rod to rotate, manipulator clamping, manual support, etc. The rotating rod is very fast when rotating. It is easy for the drill pipe to collapse or collapse, and due to the heavy weight of the drill pipe itself, safety accidents are prone to occur;

[0006] Second: During the drilling process, due to the long drilling depth, multiple drill pipes are required to complete the drilling work, and the drill pipes need to be manually moved during use, and the drill pipes are transported to the designated area one by one , and then complete the connection work of the drill pipe. It takes time and manpower to move the drill pipe, and the weight of the drill pipe is relatively large, which is likely to cause safety accidents
