摘要
半空间刻度是计算阵列感应测井线圈系误差的重要方法。研究应用COMSOL软件准确计算阵列感应测井半空间响应的方法,解决了点源施加、合理网格剖分、高精度数据采集等问题。在验证计算有效性基础上,计算分析阵列感应MIT在水平或垂直放置时的半空间响应特性,提出了基于数据库的线圈系误差校正方法,解决了如何确定等效高度和大地电导率问题。
Half-space calibration is an important method to calculate the array induction logging coil system error.COMSOL software solved the problems such as point source applying,reasonable meshing,high-precision data acquisition and etc.On the basis of verifying the effectiveness of calculation,half space response of MIT which is placed horizontally or vertically is computed and analyzed.A new sonde error correction method based on databank is proposed.With it equivalent height and earth conductivity can be determined.
