摘　　要：二氧化碳捕集、驱油与埋存(CCUS-EOR)是最现实可行的规模化减碳技术,也是大幅度提高低渗透油田采收率的关键技术。梳理了国外CCUS-EOR发展的主要历程及其产业化进展,总结了中国CCUS-EOR技术攻关成果和矿场试验进展情况,分析了CO_(2)捕集、输送、驱油与埋存等全产业链的发展现状、面临问题与挑战,指出了中国CCUS-EOR规模化应用在驱油增产、埋存减碳等方面的巨大潜力和发展前景。提出目前中国CCUS-EOR正处于矿场试验向产业化发展的关键时期,需要针对中国陆相油藏的特点,发挥油田CO_(2)驱油可驱储量丰富、地下埋存空间巨大、地面基础设施完善和井筒注入通道分布广泛等优势,积极与碳源排放企业合作,加快攻关低浓度CO_(2)的低成本规模捕集、超临界长距离输送、更大幅度提高采收率和埋存率、安全规模埋存等核心关键技术攻关和示范工程建设,构建CCUS-EOR全产业链理论技术标准体系,支撑和推动工业化规模应用,以创新链引领CCUS-EOR新兴产业链快速效益发展。Carbon dioxide capture,EOR-utilization and storage(CCUS-EOR)are the most practical and feasible large-scale carbon reduction technologies,and also the key technologies to greatly improve the recovery of low-permeability oil fields.This paper sorts out the main course of CCUS-EOR technological development abroad and its industrialization progress.The progress of CCUS-EOR technological research and field tests in China are summarized,the development status,problems and challenges of the entire industry chain of CO2 capture,transportation,oil displacement,and storage are analyzed.The results show a huge potential of the large-scale application of CCUS-EOR in China in terms of carbon emission reduction and oil production increase.At present,CCUS-EOR in China is in a critical stage of development,from field pilot tests to industrialization.Aiming at the feature of continental sedimentary oil and gas reservoirs in China,and giving full play to the advantages of the abundant reserves for CO2 flooding,huge underground storage space,surface infrastructure,and wide distribution of wellbore injection channels,by cooperating with carbon emission enterprises,critical technological research and demonstration project construction should be accelerated,including the capture of low-concentration CO2 at low-cost and on large-scale,supercritical CO2 long-distance transportation,greatly enhancing oil recovery and storage rate,and CO2 large-scale and safe storage.CCUS-EOR theoretical and technical standard system should be constructed for the whole industrial chain to support and promote the industrial scale application,leading the rapid and profitable development of CCUS-EOR emerging industrial chain with innovation.
