Abstract: The development of continental shale oil in China faces the bottleneck of low production of single well, rapid decline and low ultimate recovery. Therefore, the CO₂ enhanced oil recovery (EOR) technology is necessary to be researched in advance. The development process of CO₂ EOR technology in North America is systematically analyzed, and the applicability and prospects of this technology are discussed by combining with the conditions of domestic continental shale oil resources. The result shows that the shale oil plays in China are characterized by a significant variation on crude oil viscosity, formation pressure coefficient and mineral compositions, which have distinctly different challenges for benefit development and largely different CO₂ EOR mechanisms. As a result, a targeted application index of CO₂ EOR technology is required for various shale oil plays, as well as a technical adaptability evaluation criterion. Meanwhile, efforts should be intensified in all links of field application of CO₂ EOR technology, and clear national financial support should be sought actively. Considering the technology prospects and resource conditions, it is proposed to build a pilot demonstration area for CO₂ EOR application in Jimsar shale oil block in Junggar Basin and establish an integrated technology and policy supporting system, so as to effectively promote the development of CO₂ EOR technology, ensure the domestic energy security and support to achieve the strategic goal of carbon neturality.
