摘　　要：针对高温高压干热岩钻井定位轨迹探测设备存在耐高温高压性能差、稳定性差、测量精度不高、电能消耗大等问题,研制一套高温钻孔测斜装置,解决高温高压多点连续钻孔测斜及测温问题。选择耐高温元器件,设计控制和测量电路;采用自动间歇供电方法,减少散热,降低功耗;设计保温探管、承压探管,利用ANSYS有限元软件对承压外管的屈服强度和保温探管的温度场与压力场进行耦合分析和校核。最后进行仿真测试和野外试验,根据测试数据表明,设备能在280℃和12 MPa高温高压环境条件下实现深井倾角、方位角、工具面向角及温度的测量。In the detection of high-temperature and high-pressure dry heat rock drilling location trajectory,the in-strument 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 tem-perature 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.
