The carbon capture，utilization and storage（CCUS）technology is an effective means of reducing carbon emissions and an important supporting technology for achieving China’s carbon peaking and carbon neutrality goals. The carbon dioxide（CO₂）flooding，namely the application of CCUS for enhanced oil recovery（CCUS-EOR），is one of the main CO₂ utilization methods in this regard. This paper summarizes the whole process of CCUS-EOR and systematically describes the development status and prospects of capture technologies，transport methods，and flooding and storage processes. For the capture process，emphasis is laid on analyzing the advantages and disadvantages，costs，and development trends of different CO₂ capture technologies，and China’s problems in large-scale carbon capture costs and capture processes are exposed. In terms of the transport process，the challenges，such as pipeline construction，pipeline transport processes，and pipeline transport equipment，faced by supercritical pipeline transport are highlighted. As for the CO₂ flooding process，the deficiencies in the technical level，application scale，and production effect of the CCUS-EOR technologies in China are examined.As far as the CO₂ storage process is concerned，storage safety is analyzed，and the methods of monitoring possible CO₂ leakage are listed. The guidance of the carbon peaking and carbon neutrality policy，the source-sink matching around major oil·producing basins，and the low-permeability reservoirs with abundant reserves have laid a solid foundation for the development of CCUS-EOR technologies in China. Nevertheless，China’s large-scale low-concentration capture technology，longdistance supercritical pipeline transport technology，large-scale flooding and storage technology，and intelligent monitoring technology still lag behind the more well-established industrial CCUS technologies abroad. In response，this paper puts forward suggestions from the perspectives of policy guidance，technological breakthrough，and supporting infrastructure construction，and they can provide a reference for the development of large-scale CCUS technologies in China.
