摘　　要：基于对高频电磁波测井响应特征的认识 ,提出了一种利用相位差和幅度比测井曲线提取地层参数的特征识别方法 ,即利用测井响应对地层深度的相对一阶导数绝对值曲线的极大值峰的位置来确定地层的纵向边界 ,由其极小值处的测量值来确定地层的电参数视值 。In light of the response character of the high frequency electromagnetic wave logging(HFEL), a characteristic recognition method for picking formation parameters from the measured logs is brought forward. The method described in this paper begins by picking bed boundaries from the position of maximal value points of the relative first derivative absolute value curves of logging responses to depth, and spreads by picking bed electric parameter apparent values from the logging responses at the minimal value points of the relative first derivative absolute value curves of logging response to depth. As a result, we found that the method is successful.
