Title: Study on Flooding Efficiency and Affecting Factor of Shinan J_2t_2 Reservoir
Abstract: The flooding efficiency of heterogeneous waterflooding sandstone reservoir was one of the essential contents in the exploitation process. Flooding efficiency and chief energy displacing pattern were varied with exploitation process, by calculating the water storage rate,cumulative water-oil ratio and energy displacement index to determine the flooding effect, the later development plan was adjusted, exploitation effect was improved. It is considered that Shinan J2t2 reservoir is displaced by elastic energy early, it is displaced by water energy after that the water storage rate is lower with exploitation, flooding efficiency also, and produced water increase quickly. It is pointed out that precipitation facies, reservoir heterogeneity, type of reservoir medium, hydraulic fracture direction and fracture half length have an impact on the flooding efficiency.
