摘　　要：碳捕集、利用与封存技术(CCUS)是减少碳排放的有效手段之一,是实现中国双碳目标的重要技术保障。CO_(2)驱油(CCUS-EOR)是其中最主要的CO_(2)利用方式。梳理了CCUS-EOR整个流程,系统阐述了捕集技术、输送方式和驱油封存过程的发展现状及发展前景。针对捕集过程,着重分析了不同CO_(2)捕集技术的优缺点、成本及其发展趋势,指出了中国在大规模碳捕集成本和捕集工艺方面存在的问题;针对输送过程,着重分析了超临界管道输送面临的挑战如管道建设、管输工艺和管输设备等方面;针对CO_(2)驱油过程,着重分析了中国在CCUS-EOR技术上的技术水平、应用规模及生产效果方面存在的问题;针对CO_(2)封存过程,侧重对埋存的安全性进行分析,列举了可能的CO_(2)泄漏监测方法。中国的双碳政策指引、主要产油盆地周边源汇匹配、储量丰富的低渗透油藏都为CCUS-EOR的发展奠定了良好的基础,但在大规模低浓度捕集技术、长距离超临界管道输送技术、规模化驱油埋存、智能化监测技术等方面与国外较为成熟的工业化CCUS相比还存在一定差距。针对这些差距,从政策引导、技术攻关和配套基础设施建设上提出了相关建议,对于中国大规模CCUS技术的发展具有一定参考意义。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(CO_(2))flooding,namely the application of CCUS for enhanced oil recovery(CCUS-EOR),is one of the main CO_(2) 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 CO_(2) 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 CO_(2) 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 CO_(2) storage process is concerned,storage safety is analyzed,and the methods of monitoring possible CO_(2) 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
