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。
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 pro- posed. The computer program was designed. The numerical simulation results show that the meshless method is suitable approach to reservoir simulation.
