提升测井曲线分辨率的一种反演方法

摘要

In order to solve the ill‐posed problem of longitudinal resolution of logging curve used by the first kind of operator equation ,based on the Tikhonov regularization method ,and using the amended Backus‐Gilbert method ,the longitudinal resolution of the logging curve was en‐hanced .Numerical simulation results show that the amended Backus‐Gilbert method is simple and effective .%为解决运用第一类算子方程求解测井曲线纵向分辨率的不适定性问题，本文基于常用的Tikhonov正则化方法，利用修正的Backus‐Gilbert方法提高测井曲线纵向分辨率，并对测井资料进行数值模拟。结果表明，修正的Backus‐Gilbert方法简单有效。
