Abstract
Taking five-spot seepage unit for example,this paper discusses a numerical simulation calculation of water flood sweep efficiency for a homogeneous formation and heterogeneous formations with six different kinds of areal distribution by using 2D and two-phase black oil model. The results suggest： Different areal heterogeneous distribution can make areal sweep more or less efficient in heterogeneous formation than that in homogeneous formation under the same water cut, and make its water cut higher or lower than that in homogeneous formation when wholly displaced. Therefore, areal heterogeneous distribution is one of the important factors affecting areal sweep efficiency. In the real field development plan, according to the impact of different areal heterogeneous distribution, deploying the flood pattern reasonably can decrease areal heterogeneity＇s unfavorable effect on the development and improve the areal sweep efficiency greatly.关键词
