Aiming at the development status of Liuxi Oilfield, waterflood stimulation is studied to improve the development effect. The process is as follows: in begin with, the displacement liquid is injected into the oil well quickly to replenish energy; then the oil well is closed a while to promote oil and water displacement; finally, let the oil well produce under a reasonable system of production. Strong water-wet, high oil saturation, the degree of fracture development and low oil viscosity are the advantages of using waterflood stimulation by analyzing related researches. Based on the reservoir engineering research, numerical simulation method which is about waterflood stimulation is established using Eclipse software. According to the numerical simulation results, assuming that injection rounds is one time, when injection volume is more, the formation pressure rises higher and the liquid sweep is wider and cumulative production is more. At the same time, the degree of stage production is increasing with the closed time lengthen. But it has the most optimum values about the closed time, and the production increase of the degree of stage production becomes significantly slow.
