Abstract

In the detection of high-temperature and high-pressure dry heat rock drilling location trajectory, the instrument has some problems, such as poor performance, poor stability, low measurement accuracy and large energy consumption. A set of high temperature borehole inclining device is designed to solve the problem of high temperature and high pressure measurement deviation and temperature measurement. Adopt high temperature resistant components, design control and measurement circuit. Automatic intermittent power supply is adopted to reduce heat dissipation and power consumption. The design of heat preservation pipe and pressure detection pipe is carried out by using ANSYS finite element software to conduct coupling analysis and check on the yield strength of the external pressure pipe and the temperature field and pressure field of the heat preservation detection pipe. Finally through the simulation test and experiment, according to the test data show that equipment can at 280℃ and 12 MPa under the condition of high temperature and high pressure environment deep dip angle, azimuth angle, tool face angle and temperature measurement.
