摘要
基于地层总纵向电导值的唯一性特征,提出用电测井曲线估算地层电阻率的一种方法——等效统计法。它比传统的方法更接近于实际的地层电阻率。其结果既可用于研究地层电阻率和岩石孔隙度的分布,也可用于与其它电磁勘探资料的联合反演解释。
<ABSTRACT> Based on the uniqueness of admittance of formation, equivalent statistics - a
method of estimating formation resistivity by using electrical log curves is introduced,which
is closer to the actual formation resistivity than traditional methods. The result is used to
study formation resistivity and distribution of rock porosity or is used to interpret joint con-
version combined with other data of electromagnetic prospecting.
