深浅侧向测井的联合反演

Associated Inversion of Deep-Shallow Laterolog

本文将地球物理中的三侧向测井模型归结为一个偏微分方程的反问题,并利用深浅三侧向测井电极系的电流与电位记录,给出了识别地层电阻率与泥浆侵入深度值的反演方法,这一方法可以为油田三侧向测井分析提供一个摆脱解释图版的途径。

In this paper, the logging model of Deep-Shallow laterolog is reduced to an inverse problem of partial differential equation and an associated inversion method is given. It can identify formation conductivity and the radius of invaded zone by current and potential records, so that interpretation charts are avoided.
