Abstract: Stochastic modeling was used to built a reservoir model which can depict effectively reservoir heterogeneity,study the uncertainty parameters distribution between wells,and reflect stochastic process in reservoir evaluation.Truncated Gaussian simulation was applied in sedimentary facies modeling,this method can reflect the facies boundary clearly,and it is suitable for terminal fan sedimentary system;Comparison of porosity and permeability feature between facies-controlled and non-facies-controlled modelings illustrated that facies-controlled modeling can better reflect reservoir physical parameter heterogeneity.Reserves fitting and production performance fitting were used to test model accuracy.The model was found to be true and reliable, and can provide a three-dimensional geologic model for subsequent numerical simulation.
