摘要
在垂直电偶极子源处于两层导电媒质上面一层的条件下,导出了电磁场在各层介质中的完整表达式,利用快速亨克儿(Hankel)变换法求解含贝塞尔(Bessel)函数的广义积分,通过计算得出了电磁场沿垂直方向的分布曲线,可为井间电磁勘探技术提供理论依据。
A complete formula of the electromagnetic fields in a layered media (two layers) is derived in this paper, provided that a vertical electric dipole is buried in the upper layer of two-layered conductive media. Hankel transform is used to calculate the integrals of Bessel function in the broad sense. The distribution of the electromagnetic fields in vertical direction is obtained numerically, and a theoretical basis is provided for the well-well electromagnetic exploration.
