Well-drilling device with cooling function and high well-drilling efficiency based on Internet of Things

Abstract

The invention relates to a well-drilling device with a cooling function and the high well-drilling efficiency based on the Internet of Things. The well-drilling device comprises a drilling rod and a cutting head. The bottom end of the drilling rod is fixedly connected with the top end of the drilling head; a cooling mechanism and an impact mechanism are arranged in the drilling rod; the impact mechanism comprises an impact hole, a bottom cover, a sliding rod, an impact block and two power assemblies; the cooling mechanism comprises a gas inlet assembly, a cooling pipe, a first one-way valve and a gas outlet pipe; and the gas inlet assembly comprises a gas inlet pipe, a circulating tank, a gas collecting pipe, a second one-way valve, a piston, a connecting rod, a rotating disc, a rotating shaft and a first motor. According to the well-drilling device with the cooling function and the high well-drilling efficiency based on the Internet of Things, the stone crushing capability of the well-drilling device is strengthened through the impact mechanism, and the drilling efficiency is improved; and in addition, the temperature of the well-drilling device is further reduced through the cooling mechanism, and the situation that the well-drilling efficiency is affected due to the overhigh temperature of the well-drilling device is avoided.

Description

technical field [0001] The invention relates to the field of coalbed methane detection equipment, in particular to a drilling device with cooling function and high drilling efficiency based on the Internet of Things. Background technique [0002] Coalbed methane refers to the hydrocarbon gas stored in coal seams with methane as the main component, which is mainly adsorbed on the surface of coal matrix particles, and part of it is free in coal pores or dissolved in coal seam water. Drilling methods are usually used to detect coalbed methane. The drill bit is one of the main drilling equipment, and the reasonable selection of the drill bit plays an important role in increasing the drilling speed and reducing the overall cost of drilling. [0003] Existing drill bits tend to undergo severe friction during the drilling process and then generate high temperature, which reduces the hardness of the drill bit, reduces the cutting amount of the drill bit, and reduces the drilling eff...

AI Technical Summary

Problems solved by technology

[0003] Existing drill bits tend to undergo severe friction during the drilling process and then generate high temperature, which reduces the hardness of the drill bit, reduces the cutting amount of the drill bit, and reduces the drilling efficiency. Not only that, the ordinary drill bit cannot generate downward impact force by itself to improve the fracture of the drill bit. The capacity of crushing rocks is low, which affects the drilling efficiency
