摘要
基于中国陆相沉积油藏大幅度提高采收率与CO_(2)长期封存的技术需求,系统梳理近年来CO_(2)驱油与埋存技术进展及实践认识,针对CO_(2)驱油与埋存向已开发老油田规模化推广应用过程中面临的关键技术需求与挑战,分析未来发展方向。先导试验阶段(2006—2019年)经过持续发展完善和应用实践,形成了第1代陆相沉积油藏CO_(2)驱油与埋存技术体系;工业化发展阶段(2020年开始)在限域相态、油藏埋存机理、油藏工程、波及调控、工程工艺、封存监测等方面取得重要进展和认识,第2代CO_(2)驱油与埋存理论技术趋于完善,支撑CO_(2)捕集、利用与埋存(CCUS)示范工程见效。为了破解CO_(2)驱油与埋存中混相程度低、气窜防控难、工艺要求高、应用场景少、协同难度大等关键技术问题,支撑CCUS实现规模化应用,需要持续加强关键技术攻关,打造促混转混、综合调控扩大波及、全流程工程工艺技术及装备、长期安全封存和监测、驱油封存协同优化调控等第3代CO_(2)驱油与埋存技术。
Based on the technological demands for significantly enhancing oil recovery and long-term CO_(2) sequestration in the lacustrine oil reservoirs of China,this study systematically reviews the progress and practices of CO_(2) flooding and storage technologies in recent years.It addresses the key technological needs and challenges faced in scaling up the application of CO_(2) flooding and storage to mature,developed oil fields,and analyzes future development directions.During the pilot test phase(2006-2019),continuous development and application practices led to the establishment of the first-generation CO_(2) flooding and storage technology system for lacustrine reservoirs.In the industrialization phase(since 2020),significant advances and insights have been achieved in terms of phase states in confined domain,storage mechanism,reservoir engineering,sweep control,engineering process and storage monitoring,enabling the maturation of the second-generation CO_(2) flooding and storage theories and technologies to effectively support the demonstration project of Carbon Capture,Utilization and Storage(CCUS).To overcome key technical issues such as low miscibility,difficulty in gas channeling control,high process requirements,limited application scenarios,and coordination challenges in CO_(2) flooding and storage,and to support the large-scale application of CCUS,it is necessary to strengthen research on key technologies for establishing the third-generation CO_(2) flooding and storage technological system incorporating miscibility enhancement and transformation,comprehensive regulation for sweep enhancement,whole-process engineering techniques and equipment,long-term storage monitoring safety,and synergistic optimization of flooding and storage.
