碳捕集、利用与封存—提高油藏采收率(Carbon Capture,Utilization and Storage-Enhanced Oil Recovery,CCUS-EOR)技术是目前最现实、有效、可行的碳减排技术,但在项目实际运行过程中存在CO2泄漏的风险.为保障CO2驱油效果和系统安全,需要对包括CO2注入、驱油、埋存、采出、集输、回注等全流程进行监测、评价、预警.通过对国内外百余个CCUS-EOR项目的文献调研,系统分析了各种监测技术的特点、应用场景、应用问题,从监测体系和关键技术两方面综述了国内外CCUS监测预警技术进展.同时,指出了 CCUS-EOR监测预警技术的发展趋势,最后针对推动CCUS-EOR发展提出了健全完善监测体系、研制关键装备、深化数智技术研究、打造工业互联网平台的建议.
The progress and development trends of CCUS-EOR monitoring and early warning technology
;Carbon Capture,Utilization and Storage-Enhanced Oil Recovery(CCUS-EOR)is currently the most pragmatic,effective,and feasible carbon emission reduction technology,but there are risk of CO2 leakage during the actual operation of the project.In order to ensure the effectiveness of CO2 flooding and safety of the system,it is necessary to monitor,evaluate and provide an early warning for the entire process operations including CO2 injection,oil displacement,CO2 storage,oil recovery,gathering and transportation,CO2 reinjection,etc.Through the literature research on more than 100 domestic and international CCUS-EOR projects,the characteristics,application scenarios and problems of various monitoring techniques are systematically analyzed.The progress of CCUS monitoring and early warning technology,both at home and abroad,is summarized from the perspectives of monitoring system and key technologies.At the same time,the development trends of CCUS-EOR monitoring and early warning technology are identified.Finally,suggestions are put forward in order to promote the development of CCUS-EOR,including developing an improved and refined monitoring system,developing key equipment,deepening the research of digital intelligence technology,and building an industrial internet platform.
