Taking the north area of Banqiao oil field as example, studies are focused on the depositional characteristics, sand Taking the north area of Banqiao Oilfield as an example, this paper studies the depositional characteristics, sand distribution and formation heterogeneity of the gravity flow depositional reservoir. Combining with the injection to production pattern, it summarizes the residual oil distribution law and the future development potentials of this kind of reservoirs after water flooding. On the basis the distribution features of various potentials and their controlling factors, it also puts forward the effective development strategies focused on enhancing reservoir recovery. The forecasting and application results show that the development results are better than before and the reservoir ultimate recovery can be increased after the application of development technology policies.[JP]
