摘要
油藏工程中通常采用的区域性数值模拟方法在当边界条件较为复杂时，实际应用遇到很大的困难。为解决这一问题，推导出稳定渗流Ｌａｐｌａｃｅ方程和Ｐｏｉｓｓｏｎ方程的边界元数模解法；给出了计算框图，用示例证明了该方法的正确性。由示例分析可知，由于边界元数模只需对研究区域的边界进行网格剖分，具有降维、计算速度快、精度高以及求解内点方便等特点。
ome difficulties are met in practice when applying numerical simulation method to oil-gas engineering in complex boundary conditions.In order to solve the problem,boundary element numerical method for steady percolation Laplace equation and Poisson equation is derived. With its calculation block diagram,the method is verified by an example.Because the method has the characteristics of reducing dimension,calculating fast,high precision and giving the inter solution easy,only dividing the research area boundaries,it should be widely used in reservoir numerical simulation.
