Firstly, based on the comprehensive research of seism, logging and geology prepared forgeological modeling, the modeling units are reasonably divided for the period I of Suizhong 36-1 Oilfield. According to the sedimentary microfacies interpretation results of single wells, combined with sedimentary microfacies assemblage of delta front, the sedimentarymicrofacies plan of each sedimentary unit is drawn up, underwhich the 3D sedimentarymicrofacies model is established. Secondly, on the basis of the facies-constrained stochastic simulation and the distribution feature of macrofacies property parameters, 3D porosity model is established by facies-constrained method. Finally, faciesconstrained method and co-simulation of porosity model are applied to establish the 3D permeability model. The dynamic data of newadjustment wells and old production wells showthat the numerical simulation result based on the geologicalmodel coincides well with the production performance of the oilfield．
