| 摘 要： | 本文引入Cole-Cole模型来模拟大地的激发极化效应，对三层水平地层且中间层为极化层的大地电磁测深的视电阻率进行了理论计算，分析了极化参数对视电阻率曲线的影响规律.采用广义逆方法对三层水平地层且中间层为极化层的模型进行了反演研究，结果表明该反演方法能够较好地确定地层电阻率的同时获得地层激电参数，应用于实际资料的反演时，反演结果与已知含油气地层的实际参数十分吻合.

| Abstract: | The paper introduces forward modeling results of the magnetotelluric method for a horizontal three-layer polarizable earth,in which the induced polarization effect is described by Cole-Cole model,and summaries some response rules on different parameters of induced polarization.Then,the inversion for the parameters of induced polarization is studied based on the generalized inverse on the three-layer polarizable model.At last,the inversion method is applied to deal with the field data of the oil-gas exploration,and satisfied results of interpretation are gained. |
