| Abstract: | 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. |
