磁性测斜工具中关于方位角校正的研究

Study on the correction of azimuth angle in magnetic measurement

本文通过对方位角计算原理的分析,得出了在不改变实际无磁钻铤长度的情况下,直接校正方位角的数学方法,结果表明,这种矫正方法都能进行消除钻具磁干扰,获得准确的方位角,可以大大减少无磁钻铤的长度,节省钻进成本。

The correct azimuth of mathematical method is obtained in this paper without changing the actual non-magnetic drill collar length by analyzing the azimuth calculation principle.The results show that the method can eliminate the magnetic drill interference to obtain the accurate azimuth angle,which can reduce the length of non-magnetic drill collar and save drilling cost.
