Abstract: This paper deals with the two-phase immiscible flow displacement problem.Only elastic compression of the rocks is taten into account,no consideration is given to capillary action.The finite element methods are applied in the solution of the pressure equation and the saturation equation.▽·(M▽P)=β^*(∂P/∂t) ▽·(Mf▽P)=Hφ(∂S/∂t) For the solution of saturation equation,the" prediction-correction" methods are also used.Based on data from the fields,models have been devised for predicting performances of water-drive reservoirs with very satisfactory results.

摘要： 我们和胜利油田协作,研究二相渗流问题,其实际背景是,用高压泵将水强行注入油层,使原油从生产井排出,这是近代采油的一种重要手段,将水强行注入油层后,水驱动油层中的石油,这就是两相渗流问题,为了对油田合理的进行开发,了解地下油、水运动规律,对油田开发来说是十分重要的.
