| 摘 要： | 采用多层层状介质模型，在忽略井眼影响的条件下，利用边界条件推导出当垂直磁偶极子源位于层状介质中任意位置时磁偶极子场的表达式；利用该表达式的递推关系，编制了计算程序，以５层地层模型为例，用计算所得数据绘制了电磁场随地层深度变化的曲线。结果表明，不论发射源及场点处于何种位置，均可以得到满意的结果且具有通用性．

| Abstract: | The theoretical formulae of electromagnetic fields excited by vertical magnetic - dipole in horizontal layered media are given without considering the effects of borehole. Accordingly, the programs are writen to fulfill the iterative formalae. As an example,a five -layer model is used to calculate the electromagnetic filed at any depth. The chart of the electromagnetic field variation with the depth in receiving - borehole is showed. |
