General Description

Due to the CO2 is a kind of gas, which has high solubility in water and crude oil, when a lot of CO2 dissolved in crude oil, the volume of crude oil will be expanded, the viscosity of crude oil will be reduced and interfacial tension between oil and water also will be reduced, to capture and purify the released CO2, then inject it into underground for oil flooding in oilfield. Which not only reduce amount of releasing CO2, but also enhance the recovery ratio of crude oil, and the economic and social benefits both are greatly improved. Compared with other flooding techniques, the CO2 flooding technique has many advantages, such as the scope of application, flooding low-cost oil production rate increased significantly, etc. For now, the CO2 flooding technique has been widely used.
