摘要
针对柱状多层介质测井模型,本文给出了井轴上沿任意方向的发射源在介质空间的电磁场的理论公式,利用递推方法可以很方便地进行数值计算.文中还分别对轴向与径向的电偶极子源和磁偶极子源共4种情况,给出了井轴上接收区磁场强度与侵入半径的关系曲线.
The theoretical formulas of electromagnetic field excited by any directed source in cylindrical multilayer media are given in this paper. It can be easily computed by using the successive derived method. The relational curves between the magnetic field strength in receiver and the invasion radius are given also on axial and radius directed source of electric-dipole or magnetic-dipole separately.
