CO2 flooding technology and sequestration is one of the main ways to avoid global warming. The existing research both at home and abroad and the experimental results show that as an oil displacement agent,the CO2 injected in the reservoir can greatly improve the recovery efficiency of oil and gas. At the same time, the underground gas storage reservoirs which have good closed conditions, can achieve long-term geologic sequestration of CO2 . In this paper, through the research of CO2 flooding
