摘要
在油田定向钻井的磁导向定位系统中，地磁偏角校正是一个不可缺少的基本要素，同时地磁偏角校正值精度直接影响定向井的导向定位精度。因此，作者提出了提高地磁偏角校正值精度的方法，并试图将地磁偏角实时自动修正技术引入我国油田定向钻井领域。
The geomagnetic declination correction is a very important basic element for magnetic guide postion system which is used in oil field to directional drill the precision of the geomagnetic declination correction directly influences the precision of the guide position precision. In the paper, a method is given to improve the precision of the geomagnetic declination correction,and the automatic correction technical of gromagnetic declination is tried to use in the domain of China oil field directional drill.
