Simulation and Analysis of Influencing Factors of Water Drive in High Water-Cut Stage of Computer Technology

This paper analyzes the influence of rhythm, scour ratio and water injection ratio on water drive condition of high water cut oilfield in Gudong 7 area of Shengli Oilfield. The research shows that because the permeability distribution of anti rhythm reservoir is conducive to the downward flow of injected water, the effect of water flooding development is better than that of positive rhythm reservoir. The greater the scouring ratio of reservoir, the smaller the distribution of remaining oil, the better the effect of water flooding development. The water flooding ratio has a great impact on the recovery degree in the early stage of oilfield development, but it is not obvious to increase the recovery degree by increasing the water flooding ratio in the high water cut stage.
