【摘要】 对求地下极化体真柯尔—柯尔参数的方法进行了研究。研究表明：诺模图校正法只在已知大地的电阻率分布并且极化体的电阻率与围岩接近时才可以使用；在大地电阻率分布未知的情况下，用反演单个测点视谱的方法不可能求得极化体的真柯尔—柯尔参数；对一些简单的大地模型可以用联合反演２ 个或多个测点视谱的方法求极化体的真柯尔—柯尔参数；先求大地模型的电阻率分布，再对单个测点的视谱进行反演也可能是１ 种求真柯尔—柯尔参数的合适的方法。更多还原

【Abstract】 Techniques for estimation of the intrinsic Cole?Cole parameters of a buried polarizable body are studied.it is shown that the nomograph correction technique can be used only if the resistivity distribution of the earth model is known and the resistivity of the polarizable body is approximate to that of the country rock,and that it is impossible to estimate the intrinsic Cole?Cole parameters by using the techniques based on inversion of the spectrum measured at one station,provided the resistivity distribution of the earth model is not known.It is alsoshown that for some simple earth model,the technique based on joint inversion of the spectra measured at two or more stations can be used to estimate the intrinsic Cole?Cole parameters.It is suggested that a techinique which determine the resistivity distribution of the earth model first and then estimate the intrinsic Cole-Cole parameters by inversion of the spectrum at one station may be a suitable techinique.更多还原
