摘要
采用水平多层介质测井模型，给出了沿任意方向的偶极子源在介质空间电磁响应的理论公式，利用递推方法可以很方便地进行数值计算．针对存在薄围岩夹层的情况，利用水平５层介质模型，在典型的地层参数与测量条件下，计算了轴向与径向的磁和电的４种偶极子源的不同物理参量的理论测井曲线，系统考察了围岩、薄夹层的影响与分层能力．
The theoretical formulas of the electromanetic response in horizontal multilayer media for any directed dipole source are given in this paper.It can be easily computed by using the successive derived method.The theoretical logging traces of various measurement physics are calculated by means of the horizontal fivelayer media model for axial and radius directed source of electric-dipole or magnetic-dipole separately.The adjacent shoulder beds effect and vertical resolution of high frequency dielectric logging are investigated systematically.
