    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.
