Abstract: Against the background of the carbon peak and carbon neutrality goals, carbon dioxide capture, flooding and storage (CCUS-EOR) can not only utilize the resources of greenhouse gases but also improve the crude oil productivity. It is the realistic and feasible technology for large-scale reduction of carbon emission. China has developed a system of injection-production engineering technology in the efforts to make the study and on-the-field experiment of CCUS-EOR technology. The system mainly includes the single-tube and double-tube injection process technology, the high gas-liquid ratio lifting technology applied alone or in combination with the gas-proof process, the anti-corrosion protection technology in combination of materials, agents and monitoring, the delayed gas channeling technology for controlling channeling by alternating injection of water and gas, and chemical plugging, the well killing process technology for shut-in under pressure or without solid-phase well killing liquid, the wellbore thawing and block-removing technology centering prevention and supplemented with chemical and physical removal methods, and the technology evaluating risks of wellbore safety. To promote effective application of the CCUS-EOR technology on a large scale, it is proposed to enhance the study of the strategic CCUS plan to determine the important and key links of technological development, bring the full CCUS-EOR process under unified consideration to create the CCUS model with the characteristics of oilfield, make study of the key technologies on the basis of the demonstration projects to realize CCUS-EOR industrialization, and establish the platform for technological research and exchange to accelerate integrated engineering and technological development.
