摘要：

In this paper the method of mechanical modeling and formula derivation is applied to explains how earth rotation causes the apparent gravity action line to deviate from the ground plumb line. Analyzing the methods of the compass pendulum and the three-accelerometer and three-magnetometer survey, this paper demonstrates the principle that earth rotation causes well inclination error and azimuth error Based on the constructed simulated drilling trajectory, the actual measured inclination angle, azimuth angle, and measured depth errors are calculated. The paper presents methods for correcting the deviation error of the compass pendulum survey method and the deviation and azimuth error of the while-drilling survey method. Finally, the correcting method is applied to the actual measured data. The accuracy and reliability of the proposed error correcting method is verified by comparing the corrected data and actual data.
