Analysis of Influence Factors and Main Control Factors Screening in CO2 Miscible Flooding
CO2 miscible flooding is an environmental recovery method to greatly enhance oil recovery by the gas of CO2 which leads global warming. In view of the fact that there are many influence factors of seepage law in CO2 miscible flooding, the four influence factors of pore structure, injection rate, reservoir heterogeneity and initial oil saturation are analyzed by means of reservoir numerical simulation to screen out the main control influence factors in this paper on the account of the characteristics of serious reservoir heterogeneity in China. The research result in this paper could provide practical guidance significance to the oilfield development program adjustment at some extent.
