In this paper, mainly through a lot of analysis, systematically expounded CO2 enhanced oil recovery technology drive the development of the status quo, and drive technology for the development of CO2 response. Hope to be able to CO2 flooding technology development provide a useful reference.This article introduces the main mechanism of CO2 flooding and its impact factors and solutions, the mechanism of integration of the miscible flooding, non-miscible drive the development of two major ways in recent years, an analysis of the typical application of the site; followed by CO2 introduced the effect of flooding factors, the main reservoir which introduced heterogeneity, fluid in the CO2 content and CO2 means the impact of a variety of injection; again introduced CO2 injection technology is currently facing corrosion, asphaltene and paraffin deposition, scaling, as well as issues such as gas, CO2 flooding for these restrictions to the development of technologies,This article introduces the main mechanism of CO2 flooding and its impact factors and solutions, the mechanism of integration of the miscible flooding, non-miscible drive the development of two major ways in recent years, an analysis of the typical application of the site; followed by CO2 introduced the effect of flooding factors, the main reservoir which introduced heterogeneity, fluid in the CO2 content and CO2 means the impact of a variety of injection; again introduced CO2 injection technology is currently facing corrosion, asphaltene and paraffin deposition, scaling, as well as issues such as gas, CO2 flooding for these restrictions to the development of technologies,CO2 injection enhanced oil recovery technology of environmental protection as a result of its own, the success rate is high, risk low, wide applicability, as well as significant, and so the effect of enhanced oil recovery characteristics of EOR technology has gradually become one of the most potential of technology, more and more widespread concern around the world.
