煤矿井下基于光纤陀螺的随钻测斜方法研究

摘要

For somespecial circumstances at coal mines,such as magnetic region or nearby rig,magnetic inclinometer can not determine the azimuth by magnetic field,so fiber-optic gyroscope can be used to complete the inclinometer work.This article research the method for MWD(Measure While Drilling) inclinometer system based on fiber-optic gyroscope at coal mines through initial alignment,then simulate the verify and validity of the method.%对于煤矿井下一些特殊环境，如磁性矿区域或钻机附近等，磁性测斜仪无法通过感应地磁场而确定钻孔方位角，可采用光纤陀螺代替磁性传感器完成测斜工作。本文主要基于惯性导航初始对准原理，完成了光纤陀螺随钻测斜方法研究，并通过仿真验证了该方法的正确性及有效性。
