Background

The carbon dioxide flooding technology is a technology for injecting carbon dioxide into an oil layer to improve the oil recovery rate of an oil field; the carbon dioxide cannot form a miscible phase when the carbon dioxide is in initial contact with the crude oil in the formation, but under the conditions of proper pressure, temperature and crude oil components, the carbon dioxide can form a miscible front; the supercritical fluid will extract heavier hydrocarbons from the crude oil and continually condense the gas displacing the front. Thus, the carbon dioxide and the crude oil become mixed-phase liquid to form a single liquid phase, so that the crude oil in the stratum can be effectively displaced to a production well; and a well slot is dug at the common oil displacement position.
