摘　　要：从分析视电阻率对地层参数的一阶相对偏导数曲线的角度 ,对高分辨率感应测井仪器的响应特性进行了系统的考察分析 ;采用轴对称二维测井模型可以同时顾及侵入和围岩对测井响应的影响 。The detective sensitivity of induction logging tool was investigated and analyzed systematically using relative first order partial derivative curves of apparent resistivity versus formation parameters. The invasion and shoulderbed effects on log responses were considered in axisymmetric 2D model. The article provides some theory bases for logging tool design and data processing.
