摘　　要：类比水平方向电偶极源和垂直方向磁偶极源电磁场求解的原理,又利用偶极沿电流方向积分是双极原理,推导出地下均匀半空间中垂直双极源电场和磁场解析计算公式.采用体积分方程法对井中垂直双极源电磁响应进行了三维模拟.它对提高井中垂直双极源圈定储层范围的精度有着非常重要的意义,同时也为井中垂直双极源三维反演问题奠定了基础.Analogous to the computing of electromagnetic field generated by horizontal electric dipole and vertical magnetic dipole, the analytic formula computing electric field and magnetic field generated by vertical bipole in homogenous half space was deduced according to the fact that the integral of dipole is bipole. 3D modeling of the electromagnetism response of borehole vertical bipole was given using body integral equation. It is very important in improving the accuracy of demarcating the reservoir boundaries. Also 3D inversion of borehole vertical bipole will base on it.
