Abstract
A large number of cores observations, analyses reveal that the sedimentary system of Wen25 block is terminal fan system. This area is now at a high water cut period, and the reservoir heterogeneity has affected the development. In order to accurately describe the reservoir, this paper built the structural model, the microfacies model using truncated Gaussian stochastic method and physical property model using facies-controlled technology. The comparison between facies-controlled and non-facies-controlled modeling reveals the former is more reliable in describing reservoir heterogeneity and can provide realistic and rational geological models for later numerical simulation and forecast.
