摘要
无网格法作为一种新型的数值方法,因其近似函数不依赖于网格而受到广泛关注。基于无网格法对油藏渗流问题的求解进行了研究。对无网格法的基本原理进行了详细的阐述;并针对油藏单相渗流问题推导了无网格法计算格式,通过实例计算验证了该方法的有效性。
Meshless method is an efficient new-style numerical method. The extensive study of the theory and applications of meshless method was clone because of the approximate function without any mesh. The meshless method was applied to the problems of single phase flow through porous media in reservoir. The fundamental theory of meshless method was explicitly described. Then the particular meshless calculating formulas were deduced. The numerical simulation results are satisfying. The case verified the validity.
