摘　　要：在研究非均匀介质双感应测井信号处理原理基础上提出了一种基于Gianzero几何因子实部的自适应非线性信号处理新方法 ,它包括自适应计算背景电导率和处理测量信号。其特点在于对趋肤效应和围岩效应同时进行校正 ;深感应经分辨率匹配后与中感应纵向分辨率一致 ,具有较高的纵向分辨率 ,使测量数据处理结果比传统处理更有利于侵入分析和薄层解释。通过计算机仿真和实际测井数据处理 ,证明该方法优于目前生产上广泛应用的处理方法。A new adaptive nonlinear signal processing method for the dual induction measurement is proposed, which is based on the real part of Gianzero geometrical factor. In this method, calculation of the background conductivity and the processing of measurements are adaptive. The method corrects the skin effect and shoulder effect simultaneously. The resolution of deep induction, processed with resolution matching, is consist with that of medium induction. The processed data are more suitable than old method for invasion analysis and interpretation of thin bed. Both computer modeling and field data processing demonstrate that it is better than the conventional method.
