摘　　要：同时考虑电导率和位移电流的影响 ,导出了基于A -Φ的一个新泛函表达式 ,并开发了能在宽频段内模拟电磁测井响应的三维有限元程序。计算了水平磁偶线圈和垂直磁偶线圈的场分布 ,也给出了倾斜井中感应测井的响应 ,最后分析了线圈半径和各向异性的影响。Considering the influence of conductivity and displacement current at the meantime, we derive a new functional formulation of A-Φ and develop a 3D Finite Element code to simulate electromagnetic well logging responses in full 3D and a wide frequency range. We compute the field distribution of a horizontal and a vertical magnetic field coil. We also give the response of induction well logging in deviated wells. Finally we analyze the influence of coil radius and anisotropy.
