| 摘 要： | 为了研究电磁测量静态效应特征,建立了多个地电模型并进行了正演模拟计算,并总结出了静态效应的特征。静态效应主要影响TM极化模式电阻率,对TE极化模式及相位影响很小,其横向上有一定的影响范围,纵向越接近地表,影响越大,对深部的异常体影响很小。并且,长电极距有利于减小静态效应的影响,地形与不均匀体影响特征基本相似。

| Abstract: | Some geoelectric models were established and computations were carried out in the paper.Based on analysis and study of the computation results, the characteristics of static effect were summed up.Static effect influence mainly resistivity in the TM polarization mode,but the influence on resistivity and phase are little in the TE polarization mode.It has a certain influence area in the transverse direction,and the closer to the surface,the more the influence will be serious in the longitudinal direction,so it has less influence on deep abnormal body.Long electrode spacing may be beneficial to reducing the influence of static effect. The terrain and the in-homogeneous media are similar to static effect. |
