| 摘 要： | 在跨孔条件下，利用积分方程法计算了孔区内外不同位置、不同产状的三维椭球体模型视电阻率异常。根据所得的典型数值模拟结果，借助视电阻率异常信息剖面图，对异常进行研究，总结了异常特征及其变化规律，并以此为基础分析和认识了其他模型的异常特征。

| Abstract: | Using the integral equation method,the apparent resistivity anomalies in three dimensional ellipsoidal model with different position and shape inside and borehole region under cross borehole condition are calculated.Based on the obtained simulation result of typical numerical value and with the help of information section of apparent resistivity anomaly,the anomalies are analyzed and studied,and the anomaly features and their variation regularity are summarized,and on this basis,the anomaly features of other models are analyzed and distinguished. |
