Abstract

The invention relates to an underground coal mine explosion-proof horizontal long drilling hole inclinometer which can measure the inclined angle of an azimuth angle, the acceleration and the deflection angle of a tool face while drilling, which belongs to the field of the geological exploration instrument. In the known technique, the drilling hole inclination survey technique is known by people for a long time, especially in the petroleum drilling and the vertical downward drilling exploration from the ground, the use of the inclinometer and the application of the inclination survey technique are relatively mature, but the use of the inclinometer under a coal mine, especially in an ultra-long horizontal drilling hole is still not explicitly reported. The long drilling hole inclinometer is composed of a probing pipe, a conversion interface, a monitor and a power supply which are connected sequentially; therefore, the explosion-proof horizontal long drilling hole inclinometer is an underground coal mine explosion-proof horizontal long drilling hole inclinometer which can measure the inclined angle of the azimuth angle, the acceleration and the deflection angle of the tool face.

Description

Directional tool of horizontal long drill hole

Technical field

The invention belongs to the exploration instrument for geology field, is the directional tool of horizontal long drill hole of the colliery downhole anti-explosion of ability interception angle lapping angle, acceleration and tools for angle specifically.

Background technology

In known technology; The drillhole inclination survey technology is familiar with by people already; Particularly in the middle of oil boring and ground prospecting by boring vertically downward; The use of deviational survey instrument and deviational survey The Application of Technology still are comparative maturity, but clearly report is not also seen in the particularly use of inclinometer in the overlength horizontal drilling under coal mine.

Summary of the invention

The directional tool of horizontal long drill hole that the purpose of this invention is to provide the colliery downhole anti-explosion of a kind of ability interception angle lapping angle, acceleration and tools for angle.

For addressing the above problem, the technical scheme that the present invention takes is:

A kind of directional tool of horizontal long drill hole, its special character is: said horizontal jumping chisel hole drill inclinometer is connected and composed by inserting tube, translation interface, monitoring monitor, power supply successively; Described inserting tube comprises cpu controller, the obliquity sensor of bowing, azimuth sensor, data acquisition unit, intrinsic safety electric source circuit, communication interface, battery pack, battery protecting circuit, charger, and its cpu controller is connected with data acquisition unit, intrinsic safety electric source circuit, communication interface respectively; Data acquisition unit is connected with azimuth sensor with the obliquity sensor of bowing respectively; Charger, battery protecting circuit, battery pack are connected with the intrinsic safety electric source circuit successively; The intrinsic safety electric source circuit is connected with the obliquity sensor of bowing, azimuth sensor, data acquisition unit; Battery protecting circuit also is connected with the intrinsic safety electric source circuit.

The present invention is with respect to prior art, and its advantage is following:

Owing to adopted the semiconductor circuit design of high integration microstructure; And adopt high diamagnetic bismuth copper as the shell encapsulating material; The data of measurement while drilling drill bit direct of travel can be carried out data communication with the monitor with serial communication interface and shown the travel track of drill bit; The built-in rechargeable battery pack energy saving type of inserting tube is supplied power, and can fully guarantee the characteristics of long distance time communication.
