摘　　要：碳达峰和碳中和发展战略以及社会经济发展对石油等能源需求量的持续增长,为CO_(2)驱油与埋存技术带来了巨大的发展机遇,也提出了前所未有的挑战。从目前中外CO_(2)驱油与埋存研究现状入手,通过CO_(2)驱油与埋存机理和影响因素分析,提出了CO_(2)驱油与埋存存在的问题和发展方向。结合实践将CO_(2)驱油与埋存研究内容总结为目标优选、相关机理实验研究、方法技术攻关、经济性评价、安全性评价和现场实践等6方面。CO_(2)驱油与埋存存在的问题主要包括:CO_(2)驱油与埋存应用的油藏类型还非常有限,CO_(2)气田分布特征及其与CO_(2)驱油与埋存目标油藏之间的时空匹配关系研究还未引起足够重视,CO_(2)驱油与埋存机理等研究还存在诸多问题,CO_(2)驱油与埋存方案设计有待优化,CO_(2)驱油与埋存经济有效性评价体系尚未建立,CO_(2)埋存安全性跟踪评价还存在一系列问题。对应的CO_(2)驱油与埋存技术研究未来发展方向包括:探索攻关CO_(2)驱油与埋存适用油藏类型和开发阶段,CO_(2)气田分布规律及其与适合CO_(2)驱油与埋存油藏之间的时空匹配关系研究,CO_(2)驱油与埋存机理研究持续攻关,CO_(2)驱油与埋存方案优化设计,CO_(2)驱油与埋存经济有效性评价和CO_(2)埋存安全性跟踪监测评价。As carbon peak and carbon neutrality development strategy and the social and economic development continuously require petroleum and other energy,CO_(2) flooding and storage technology has met great development opportunities,as well as unprecedented challenges.According to the research status of CO_(2) flooding and storage both in China and abroad,the problems and the future trend of CO_(2) flooding and storage are introduced by analyzing the mechanism and influencing factors of CO_(2) flooding and storage.Based on practice,the research contents of CO_(2) flooding and storage are summarized as six aspects,namely,target optimization,experimental study of relevant mechanisms,technical breakthrough,economic evaluation,safety evaluation,and field practice.The problems of CO_(2) flooding and storage include①CO_(2) flooding and storage technology is applied to very limited types of reservoirs.②The distribution characteristics of the CO_(2) gas field and its temporal and spatial matching relationship with target reservoirs of CO_(2) flooding and storage have not been paid enough attention.③There are still many problems in the study of CO_(2) flooding and storage mechanism.④CO_(2) flooding and storage scheme design needs to be optimized.⑤The economic effectiveness evaluation system of CO_(2) flooding and storage has not been established.⑥The tracking assessment of CO_(2) storage safety still faces a series of problems.The future trend of CO_(2) flooding and storage technology research includes①Exploring the applicable reservoir types and development stages of CO_(2) flooding and storage.②Studying the distribution law of the CO_(2) gas field and its temporal and spatial matching relationship with suitable reservoirs of CO_(2) flooding and storage.③Deepening studies on the CO_(2) flooding and storage mechanism.④Optimizing CO_(2) flooding and storage scheme design.⑤Evaluating the economic effectiveness of CO_(2) flooding and storage.⑥Conducting CO_(2) storage safety tracking monitoring and evaluation
