Forward and Inverse Methods for Calculating Cole-Cole Time Domain IP Cpectral Parameters

应用线性数字滤波方法,计算了Cole-Cole模型激电时间谱,提出了用马奎特法对实测时谱作最优化反演求Cole-Cole模型参数的方法,并通过实例说明方法效果.认为在目前国内缺少复电阻率法仪器,而时域激电仪较普及的条件下,本文对评价激电异常有实际意义.

For calculating the Cole-Cole time domain IP spectra linear digital filtering may be used. It is suggested that Cole-Cole spectral parameters may be obtained by using Marquardt method for the optimalinversion of the measured time domain IP spectra. The method suggested is proved effective by practicalexamples. At present in China time domain IP instruments are evtensively used. Apparatus for measuring complex resistivity are very few in number. Under the present circumstances, to determine specrtalIP parameters through time-domain measurements is of practical significance to IP anomaly evaluating.
