此文提出一种求解油藏渗流问题的数值计算方法,此法称为无网格伽辽金增维精细积分法。基于无网格伽辽金法(EFGM)和增维精细积分法,导出了求解非稳态渗流问题的无网格伽辽金增维精细积分的所有计算格式。结果表明,它是一种无需网格信息、格式简单、程序编制容易、计算精度和稳定性均相对较高的数值计算方法,值得推广。 In this paper, a numerical method to solve reservoir seepage problem is proposed. This method is called elementless Galerkin increasing dimension precise integration method. Based on the element free Galerkin method (EFGM) and the dimension-increasing precise integral method, all the computational schemes of the element-free Galerkin dimensioning precise integral for solving unsteady seepage problems are derived. The results show that it is a numerical calculation method without grid information, simple format, easy programming and high computational accuracy and stability. It is worth popularizing.
