At present, many oilfields in China have entered the stage of high water cut development, and the research on the methods of improving oil recovery has been paid more and more attention. Among them, the application of binary combination flooding is more and more extensive. In view of the target area, based on the fine geological modelling, this paper establishes a binary combination flooding model considering the influence of surfactant on oil-water interfacial tension, the adsorption of surfactant by rock, the shear and degradation of polymer, and the adsorption of polymer by rock. Based on the matching of reserves and production history, the development schemes under different development methods are designed and the development effect is predicted and evaluated, the influence of development mode, injection time and injection-production speed on development effect is also studied. The results show that the development effect of binary combination flooding is the best, which provides a theoretical basis for the subsequent efficient and reasonable development of the block.
