摘  要:  Simulation of flow and transport in porous media has wide applications, which include in particular the management of existing petroleum fields and the development of new oil and gas reservoirs. In this talk we will introduce a new efficient IMplicit Pressure Explicit Saturation (IMPES) scheme for the simulation of incompressible and immiscible two-phase flow in heterogeneous porous media with capillary pressure. The new algorithm is locally mass conservative for both phases and also deserves another merit that the total velocity is continuous in the normal direction. Moreover, the new scheme is unbiased with regard to the two phases and the saturations of both phases are bounds-preserving if the time step size is smaller than a certain value. We will also discuss the application of the idea of the new algorithm to develop the fully mass-conservative scheme for the multicomponent compressible flow in porous media. Some interesting examples will be shown to demonstrate the efficiency of the new algorithms.
