摘　　要：设计一种井下地震计信号方位角校正方案,直接对地震计的输出进行校正,使数据采集器记录到的数据即为仪器方位角符合要求时的信号。基于MATLAB程序的Simulink仿真工具箱计算结果表明,本文方案可应用于校正井下地震计方位角偏差,具有较高的可行性。We design a circuit for borehole seismometer to deal with azimuth deviation.This device can correct the output of seismometer before recording,so that the data recorded by data collector is the right data of the required azimuth.The results of Simulink simulation tool based on MATLAB show that the scheme can be applied to correct azimuth deviation of borehole seismometers,and is with high feasibility.
