| 摘 要： | 计算三维不均匀介质中测井响应的最常用的方法是有限元素法和有限差分法。这两种方法的缺点是数据点遍布整个三维空间 ,因而计算数据量大 ,并造成计算上的困难。文中提出一种适用于交流电测井响应计算的积分方程 ,它的数据点只分布在不同介质的分界面上 ,数据量大大降低 ,有利于进行数值计算

| Abstract: | Based upon a vectorial identity, an integral equation system concerning electromagnetic field in inhomogeneous medium is derived. The unknown functions are the field strengths along 2D boundaries separating different media. This brings about a sharp reduction to the quantity of unknowns compared with finite element mehtod and finite difference method, in which immense quantity of unknowns distributing in the whole 3D space must be manipulated. |
