摘要：There are some problems of high saturation sandstone reservoir in late development stage, such as low reservoir pressure level, low oil production volume and high water content ratio. At present, the conventional treatment measures are poor to improve the reservoir development efficiency. Through extensive investigation and comprehensive analysis, the cyclic water flooding method can effectively improve the reservoir development efficiency. This study is based on the theory of cyclic water flooding method to replace remaining oil. The numerical simulation of cyclic water flooding is carried out by establishing geological model of actual blocks. By analysing the influence of injection-production ratio, injection-production method and liquid production volume on the cyclic water flooding development efficiency, the cyclic water flooding scheme of high saturation sandstone reservoir in the late development stage is optimized.
