The structure model of Xiong an New Area is established by structural gridding on the basis of regional geology,drilling formation and well logging data.The principle of sequence stratigraphy is applied to determine isochronous interface and stratigraphic framework,and modeling parameters are selected to establish the 3D sedimentary facies model.The porosity and permeability models are established by facies-controlled sequential Gaussian simulation algorithm.The rock thermal conductivity of caprock,reservoir and bedrock in the region is obtained and the temperature field model of Wumishan Formation is established according to the actual measurement.The physical parameter distribution comparison,probability model consistency and fitting are finally used to verify the geological model.The results show that the probability distribution characteristics of porosity and permeability of this geological model are basically consistent with the log interpretation curve data and initialization data,indicating that consistency between the model and geological recognition is more than 90％thus the geological model is reasonable.
