This article reviews the development of high-pressure injection air technology and its recent advances, listing several typical air injection projects and their main parameters. Analysis of high-pressure injection of air technology, oil displacement mechanism that the light crude oil injection air is a kind of flue gas drive and thermal effects dominated the oil displacement. Based on the analysis of the geological characteristics of a large number of air injection projects in the United States, the geological influencing factors and reservoir screening criteria for air injection projects are summarized, including indoor screening criteria and mine screening criteria. From the aspects of production wells, injection wells and other production facilities, the main problems and solutions in the safety of air injection are analyzed. The results of laboratory experiments and field applications show that high-pressure injection of air-displacing oil technology is a cost-effective method to enhance oil recovery, especially for low-permeability, high-pressure, deep and light oil reservoirs, The third oil recovery is also suitable for secondary oil recovery in low permeability oilfields with water injection difficulties. It can also be used in combination with water injection technology to maintain formation pressure and maintain stable gravity and oil displacement. Concerned about the safety of air injection Note also gradually eased, high pressure air injection technology is promising.
