本文概述了井中复电阻率谱(CR谱)的两种正演方法:用解析公式作理论计算及水槽模型实验。特别着重介绍了从CR频率谱求时间谱的转换计算及时谱的常用参数表达形式。介绍了获取井中CR谱的水槽模型实验技术并给出了一些模型实验曲线。这些成果表明,从模型实验曲线总结的CR谱性态特征及分布规律与理论计算曲线总结的规律完全相符。 This paper outlines two forward methods of well resistivity spectra (CR spectra): using analytic formulas for theoretical calculations and sink model experiments. In particular, the conversion of time spectrum from CR frequency spectrum and the expression of common parameters of time spectrum are emphatically introduced. This paper introduces the experimental technique of sink model for obtaining CR spectrum in well and gives some experimental curves of model. These results show that the characteristics and distribution of CR spectra summarized from the model experimental curves are in good agreement with the laws of theoretical calculation.
