Although there are some review papers on carbon capture, utilization and storage (CCUS), hardly any of these reviews are focused on the role of CO enhanced oil recovery (EOR) in accelerating carbon neutrality in China. In this review, strategies to achieve carbon neutrality is briefly but critically discussed, followed by a review of CO-EOR as a promising technology. Especially, data analysis, including the number of publications on China's carbon neutrality, per capita CO emissions, China's power generation, and the crude oil production of China's large oilfields, is carried out to make the discussion more comprehensive. Given the large amount of coal consumed in China, the high percent of electricity generated with coal, and the slow penetration of renewables already observed, it seems unlikely that 2060 targets will be met without CCUS. In order to achieve carbon neutrality, both reduction in carbon emissions and increase in carbon sequestration are inevitable. Furthermore, it is concluded that CO storage through EOR is likely to have a bright future. However, there are some critical issues to be solved, including the technical issues, leakage and safety issues, cost issues, policy issues, etc. In order to turn CO-EOR into a reliable and more favorable technology, more research and efforts are needed to solve these issues, including advancing carbon capture technologies, improving storage technologies, developing effective monitoring technologies, deploying government support and incentive policies, etc.
虽然有一些关于碳捕获、利用和储存 (CCUS) 的综述论文，但几乎没有任何一篇综述专门关注 CO 强化采油 (EOR) 在加速中国碳中立方面的作用。在这篇综述中，简要但批判性地讨论了实现碳中立的策略，随后回顾了 CO-EOR 作为一种很有前途的技术。特别是，对中国碳中立的相关数据进行了分析，包括中国碳中立的出版物数量、人均 CO 排放量、中国的发电以及中国大型油田的原油产量，以使讨论更加全面。考虑到中国消耗的大量煤炭、煤炭发电的高比例以及可再生能源的缓慢渗透，在没有 CCUS 的情况下，似乎不太可能实现 2060 年的目标。为了实现碳中立，减少碳排放和增加碳封存都是不可避免的。此外，结论认为，通过 EOR 进行 CO 储存可能有一个光明的未来。然而，仍然存在一些亟待解决的关键问题，包括技术问题、泄漏和安全问题、成本问题、政策问题等。为了使 CO-EOR 成为一种可靠且更有利的技术，需要进行更多的研究和努力来解决这些问题，包括推进碳捕获技术、改进储存技术、开发有效的监测技术、部署政府支持和激励政策等。
