摘要 

在频谱激电法中利用剩余电磁效应(REM)研究地下电性分布已引起人们的重视。本文基于对数值计算结果的分析指出,选择适当高频fG,以偶极装置观测视复电阻率的相位φs0(fG),用相应条件下均匀大地的视复电阻率相位理论值(fG)对其作归一,所得比值参数φs0(fG)/(fG)是表示剩余电磁效应的理想参数。文中还结合数值计算结果和野外实测资料,分析了这一参数的异常特征和在油气探测中的应用效果。

Abstract

In frequency spectrum IP method, the application of residual electroma gnetic effect to the study of the distribution of underground electricity has aroused much interest. Based on an analysis of numerical calculations, this paper points out that, when the high frequency fG is properly chosen, the phaseφs(fG) of apparent complex resistivity is observed by dipole device, and it is normalized by the phase theoretical valueφs0(fG) of the apparent complex resistivity of uniform ground under the corresponding condition, then the ratio φs(fG)/φs0(fG) obtained is the ideal parameter representing residual electroma gnetic effect. Combining numerical calculations with field data, the paper also makes an analysis of the anomalous character of this parameter and its effect in the prospecting for oil and gas.
