CO_(2)提高油气采收率与地质封存关键技术发展建议

Development Suggestions for Key Technologies of CO_(2)-Enhanced Oil and Gas Recovery and Geological Sequestration

CO_(2)提高油气采收率与地质封存是中国保障能源安全以及发展低碳经济的关键技术,为中国实现“碳达峰、碳中和”目标提供重要技术支撑。文章梳理了CO_(2)提高油气采收率与地质封存的基本机制,总结了世界范围内CO_(2)提高油气采收率与地质封存的关键技术及其应用现状,从生态保护和经济发展的角度展望了CO_(2)提高油气采收率与地质封存技术商业化的发展前景,详细分析了该技术在中国实现商业化所面临的挑战,并提出了相关建议。作为碳排放与能源消费大国,应当结合中国基本国情,通过财政补贴、完善碳税制度及碳市场来支持CO_(2)提高油气采收率与地质封存技术的推广,同时加紧科研攻关与技术合作,健全碳捕集、利用与封存(Carbon Capture,Utilizationand Storage,CCUS)全产业链,引领经济健康与持续发展。

CO_(2)-enhanced oil and gas recovery and geological sequestration are the key technologies for ensuring energy security and developing a low-carbon economy in China,and they provide important technical support for China to achieve carbon peak and neutrality.This paper reviewed the basic mechanism of CO_(2)-enhanced oil and gas recovery and geological sequestration,summarized the key technologies of CO_(2)-enhanced oil and gas recovery and geological sequestration worldwide and their application status,and looked forward to the commercialization of CO_(2)-enhanced oil and gas recovery and geological sequestration technologies from the perspective of ecological protection and economic development.The challenges during the commercialization of these technologies in China were analyzed in detail,and some suggestions were put forward.As a country with great carbon emissions and energy consumption,China should support the promotion of CO_(2)-enhanced oil and gas recovery and geological sequestration technologies through financial subsidies or by improving the carbon tax system and carbon market based on national conditions,and it should strengthen scientific research and technical cooperation,so as to improve the whole industrial chains of carbon capture,utilization,and storage(CCUS)and give guidance for the healthy and sustainable development of the economy.
