摘要: 应用无网格法对油藏中的油水两相渗流问题进行了研究。无网络法与以往数值方法不同,只须用节点来离散求解域,而不需要网格。阐述了油-水两相渗流数学模型的建立和无网格法的基本原理,推导了油水两相渗流问题的无网格计算格式,并编制了相应的计算程序,其计算结果比较合理。

Abstract: The meshless method was applied to analyze oil water two-phase flow problem. This method only needs nodes instead of mesh to scatter domain as compared with the previous numerical methods. The mathematical model of oil water two-phase flow was established. The fundament of the meshless method was described, and the calculation formulae for the meshless method were proposed. The computer program was designed. The numerical simulation results show that the meshless method is suitable approach to reservoir simulation.

Key words: meshless method, reservoir numerical simulation, oil water two-phase flow, mathematical model
