The Chang_3 oil measures in the H-152 block of the Huachi Oil Field are assigned to the low-porosity and low-permeability reservoirs in the middle and later stages of the oil field development. Judged from geological and sedimentary features, the Chang_3 oil measures dominantly consist of the delta front and prodelta subfacies deposits including the subaqueous distributary channel, interdistributary bay, channel mouth bar, diatal bar and prodelta mud microfacies. These sedimentary microfacies are constructed by using the deterministic method, and the modeling of the reservoir physical properties are proposed by using the sequential Gaussian similation. This model is helpful to the further development of the H-152 block of the Huachi Oil Field.
