Abstract
The two-phase oil-water flow in naturally fractured reservoirs and its numerical methods are introduced in this paper, where the fractured reservoirs are modeled by the dual porosity method. An efficient numerical scheme, including the finite difference (volume) method, CPR-FPF preconditioners for linear systems and effective decoupling methods, is presented. Parallel computing techniques employed in simulation of the two-phase flow are also presented. Using these numerical scheme and parallel techniques, a parallel reservoir simulator is developed, which is capable of simulating large-scale reservoir models. The numerical results show that this simulator is accurate and scalable compared to the commercial software and the numerical scheme is also effective.
