摘　　要：从麦克斯韦方程及本构关系出发，导出了频率域中的电磁波动方程。采用有限差分方法，对波动方程求数值解。设计的程序可模拟实际的测井过程。程序执行后给出模拟测井曲线。数值模拟试验表明，多频电磁波测井对区分油水层是成功和有效的。We derive out frequency domain electromagnetic wave equation from Max well′s equation and constitutive relation. We use finite difference method to solve electromagnetic wave equation. Designed program can simulate actual logging process. A simulative well log were obtained after executing program. The results show that muti-frequency electromagnetic wave propagation logging is efficient and successful in differentiating oil-water layers.
