利用测井响应对地层参数的相对一次偏导数曲线 ,对高频电磁波测井的探测灵敏度进行了系统的考察分析 ,发现高频电磁波测井响应对地层纵向边界相当敏感 ,其敏感程度往往超过了对电参数的敏感程度 ,但对纵向边界的敏感反映区集中在边界附近的一个小区域里 ,除薄层外对电参数的敏感反映区主要集中在本层内 ,表明高频电磁波测井的分辨率是比较好的 ,其中相位差曲线的分辨率又优于幅度比曲线
Based on the relative partial derivative curves of logging response to formation parameters, the detection sensitivities of high-frequency electromagnetic wave logging were systematically investigated and analyzed. It was found that the response of high-frequency electromagnetic wave logging was quite sensitive to the longitudinal boundary of the stratigraphy, and its sensitivity was often over Sensitive to the electrical parameters. However, the sensitive reflection of the longitudinal boundary is concentrated in a small area near the boundary. The sensitive reflection of the electrical parameters except for the thin layer is mainly concentrated in this layer, indicating that the high-frequency electromagnetic wave logging Resolution is better, in which the phase difference curve resolution is better than the amplitude ratio curve
