In order to increase the pertinence of regulating measures at the late water flooding development of F4 reservoir, analytic hierarchy process was used to evaluate the geologic development factors which influence the water flooding effect. A multi-factor comprehensive evaluation method was developed. The results indicated that the permeability of the thin layers which water was injected into, injection-production well spacing and the injection pressure were the major factors which influence water flooding effect. The application of the method in the F4 reservoir showed its practicality and effectiveness.
