Numerical Simulation Study on Advanced Water Injection for Fuyang Ultra-Low Permeability Fractured Reservoir

Abstract:

According to the features of low porosity and low permeability fracture as well as small scale of channel development, frequent sedimentary facies changes of planar sandstone, poor connectivity, large variation of sequence thickness and great development difficulties for oil layer in Fuyang Oilfield. In this paper, on the basis of fully considered of fracture features, built a more accurate 3-D geological model. And on the basis of the history matching, determined the formation pressure maintenance level under different injection-production ratio and rational water-flooding timing by the simulation of the different programs in the process advanced water injection development. The results show that: the reasonable injection-production ratio of Fuyang oil layer is 1.4, and the rational water-flooding timing is three months after advanced water injection. This provides theoretical guidance for the large-scale development of Fuyang oil layer, and also provides the technical basis for the developing of the other low permeability fractured oil field by advanced water injection.
