感应测井测得的是地层视电导率，获得地层真电导率的方法之一就是将感应测井响应进行反滤波处理．如果使用空间频域滤波的方法设计反滤波因子，由于感应测井响应函数存在盲频率，会产生严重的吉布斯效应．本文用Ｒｅｍｅｚ交换法设计反滤波因子，能够有效地减弱吉布斯效应，得到较理想的真电导率曲线． Induction logging measures the apparent conductivity of the formation. One of the ways to obtain the true conductivity of the formation is to reverse the induction logging response. If spatial filtering is used to design the inverse filtering factor, there is a serious Gibbs effect due to the blind frequency of the induction log response function. In this paper, Remez exchange method is used to design the inverse filter, which can effectively reduce the Gibbs effect and obtain the ideal true conductivity curve.
