【摘要】 本文给出了一种把卡尼亚视电阻率换算为全区电阻率的便利方法.通过二、三层电性断面的模型试算及实测CSAMT资料的计算结果,说明在远区该方法的结果等于卡尼亚视电阻率,在近区和过渡区则明显改善了卡尼亚视电阻率的畸变.该方法能增加CSAMT的勘探深度,更好地反映地电断面的特征.更多还原

【Abstract】 This paper presents a convenient method for convert the Cagniard resistivity to the all-time apparent resistivity.Computation of the apparent resistivity of the two or three layer sections and the result calculated by the CSAMT can reflect that in far-field area the results are equal to Cagniard resistivity,but in near-field area and transient area,the results have greatly improved the strong distortion of Cagniard resistivity.This method will increase the depth of CSAMT exploration and reflect the changes of the vertical subsurface electric vividly.更多还原
