Abstract

The invention provides an underground coal mine drilling anti-tilt device based on coal mine engineering. The underground coal mine drilling anti-tilt device comprises a clamping block, a balance sensor and an eccentric stability controller; the clamping block is symmetrically arranged in two parts, bracket bodies are fixedly and vertically welded to the front outer wall and the rear outer wall ofthe clamping block, and bracket bodies are vertically disposed on the inclined walls of the left side and the right side of the clamping block; the four corners of the front side wall and the rear side wall of the clamping block are fixed with bolts; and upper partition plates and lower partition plates are separately arranged on the middle parts of the bracket bodies horizontally. According to the underground coal mine drilling anti-tilt device based on coal mine engineering, the various structures are matched, so that in the underground coal mine drilling of the coal mine engineering, the device can ensure the directionality of drilling and avoid that the device is biased due to the tilt in the drilling butt-joint process, and can be adjusted automatically and timely according to the inclination of the device vibration in the drilling process.

Description

technical field [0001] The invention relates to the technical field of oil and gas drilling engineering, and more specifically relates to an anti-tilt device for underground coal mine drilling based on coal mine engineering. Background technique [0002] Drilling is a basic means of exploration and development of underground resources such as oil and gas, and it is also a capital- and technology-intensive professional project. Advanced drilling technology has played an irreplaceable role in accelerating the exploration and development of oil and gas resources and reducing the cost of exploration and development operations. Therefore, research on drilling technology and drilling tools is of great practical and strategic significance to improve the efficiency and economic benefits of exploration and development of underground resources such as oil and gas in my country, and to participate in the competition in the world technology market. [0003] Through the technical analys...
