摘要 为实现中国碳达峰、碳中和的长远目标,将化石能源燃烧生成的CO_(2)捕集后注入到高含水油藏,不仅可提高原油采收率,而且能在油层中实现CO_(2)地质封存,有利于实现油气增产和降低碳排放的双重目标。针对高含水油藏的特点,从CO_(2)驱油和地质封存机理、赋存方式、埋存量计算方法以及CO_(2)运移、泄漏风险预测与评价等方面进行了全面回顾。基于高含水油藏CO_(2)驱油与地质封存的中外研究现状,结合与之密切相关的科学领域及其矿场面临的难题,提出了CO_(2)与储层岩石和流体反应、驱油机理和封存方式、赋存量、封存效率、泄漏与风险防控等亟需深入研究的10个关键问题,为CO_(2)驱油与地质封存研究方向及产业化技术储备提供参考。CO_(2)驱油与地质封存问题的解决,对服务于“碳减排”和“碳增汇”,实现中国的碳达峰、碳中和战略目标具有重要意义。 To realize long-term objectives of carbon peaking and neutrality in China,injecting captured CO_(2) generated by fossil fuel combustion into high-water-cut reservoirs may not only enhance oil recovery,but realize CO_(2) geological storage in oil layers.This is conducive to achieving the dual goals of increasing oil and gas production and reducing carbon emissions.In view of the characteristics of high-water-cut reservoirs,a comprehensive review is carried out from the aspects of CO_(2) flooding and geological storage mechanisms,storage modes,storage-capacity calculation methods,CO_(2) migration,and leakage-risk prediction and evaluation.Based on the research status of CO_(2) flooding and geological storage in high-watercut reservoirs in China and abroad,as well as the closely related scientific fields and the problems faced by mines,this paper puts forward ten key issues needing further research,such as reaction of CO_(2) with reservoir rocks and fluids,CO_(2) flooding mechanism and storage mode,storage capacity,storage efficiency,and leakage-risk prevention and control.This provides a reference for research directions of CO_(2) flooding and geological storage,as well as industrial technology reserves.The solution to the key issues of CO_(2) flooding and geological storage is of great significance for serving“carbon emission reduction”and“carbon sink increase”to achieve the strategic goals of carbon peaking and neutrality in China.
