摘要
针对定向钻井的特殊技术要求 ,提出在无陀螺仪的情况下 ,仅运用加速度计和磁传感器来确定井孔相对磁北和真北的方位以及相对当地垂线的倾斜角的方法 ,给出了测斜、定向的原理及计算公式。仿真结果显示该方法具有良好的效果 。
An effective approach of measuring the drilling well's gradient and azimuth angle is presented which uses only one threeaxis accelerator and one magnetic sensor to meet the special technique requirement of the directional drilling,and its principle and formula are also given.In the end,the simulations are made which show that it is an effective and practicable approach.
