大地电磁测深法 (MT)中的静态效应使实测的视电阻率和相位曲线出现畸变 ,导致反演解释得出错误的结果 .基于大地电磁测深响应在高频时具有一维响应特征 ,作者提出了对阻抗张量或实测的电场分量实施静态校正的方法 ,由高频的实测数据求取电场畸变张量和静态校正张量 ,而后对全频域的实测阻抗张量进行校正 ,以获得无静态干扰的张量 .实践结果表明 ,通过校正静态效应 ,消除了静态效应对视电阻率和相位曲线产生的畸变现象 The static effect in the MT can distort the measured apparent resistivity and phase curve, which leads to wrong results in the interpretation of the inversion. Based on the one-dimensional response characteristic of the electromagnetic electromagnetic sounding response at high frequency, The authors propose a method of static correction of the impedance tensor or the measured electric field component, obtain the electric field distortion tensor and the static correction tensor from the measured data of high frequency, and then correct the measured impedance tensors in the whole frequency domain The tensor without static disturbance is obtained.The practical results show that by correcting the static effect, the distortion caused by the static effect on apparent resistivity and phase curve is eliminated
