Intelligent directional drilling system and directional drilling method thereof

Abstract

The invention aims to provide an intelligent directional drilling system and a directional drilling method thereof. The intelligent directional drilling system involves a drill bit, a display module and a central processor module, wherein an emitter is arranged inside the drill bit, a receiver is arranged inside the display module, the emitter and the receiver are combined with the central processor module to form a directional drilling system for intelligent directional drilling of the drill bit, the emitter comprises a data modulation module, a nine-axis sensor and a power supply, and the receiver comprises a power supply, a data adjustment module and a display module. The intelligent directional drilling information system of the drill bit is timely and effectively adjusted and rectified so as to effectively ensure the drilling quality, find the drilling problem effectively and timely, improve the feedback timeliness, reduce the unnecessary cost, and promote the industry developmenteffectively.

Description

technical field [0001] The invention is mainly used in the fields of drilling technology and structural technology, and mainly relates to an intelligent directional drilling system and a directional drilling method thereof. Background technique [0002] In the field of drilling, the quality of the borehole is an important indicator to verify the quality of the drilling, including depth, length, inclination and position. In the traditional drilling method, the ground vertical drilling machine is mainly used to detect the drill through the length and quantity of the drill pipe. The depth of the hole, but the verticality (or inclination) of the drilling is difficult to measure. When the inclination angle is large or exceeds the expected position angle, it is difficult to find out in time. The position must be corrected by adjusting the drill pipe (drill bit), prolonging the construction period and destroying the Drilling and ground level non-excavation drilling models, through ...

[0002]In the field of drilling, the quality of drilling is an important indicator to verify the quality of drilling, including depth, length, inclination and position. The vertical drilling machine detects the drilling depth by the length and quantity of the drill pipe, but it is difficult to measure the verticality (or inclination) of the drilling hole. When the inclination angle is large or exceeds the expected position angle, it is difficult to find it in time. Adjust the drill pipe (drill bit) to correct the position, prolong the construction period, and at the same time destroy the drill hole and the ground level trenchless drilling machine. Through the signal rod in the drill bit, the ultrasonic signal is continuously emitted, and the drill bit is directly above the ground through the hand-held receiver. The position of the receiver can be monitored (you can see the slope and depth of the signal bar and the direction of the inclined panel at the front of the drill bit), but when it is necessary to cross a river or a mountain, it is difficult to implement the manual hand-held receiver, and the signal transmission is attenuated , at the present stage coal mine underground tunnel drilling machine, but this method needs to disassemble the drill pipe and drill bit many times, which takes a long time and a large amount of engineering, and the problem is not found in time, and it is difficult to adjust again, and the position and angle of the drill hole and the drill hole are difficult to meet the requirements of the coal mine. There are design requirements for gas drainage, but there are also potential safety hazards and high labor costs. The drilling methods used at this stage will have abnormal problems, feedback lag, low detection accuracy, and damage to the borehole. The operation is difficult and costly. High, time-consuming, and largely a potential safety hazard
