吉林油田CCUS-EOR技术攻关与实践新进展OA北大核心CSTPCDEI
New research and practice progresses of CCUS-EOR technology in Jilin Oilfield
CO2 捕集、埋存与提高原油采收率(CCUS-EOR)技术可大幅度提高原油采收率并实现CO2 有效埋存,同时兼具减碳、增油两大功能,是落实"双碳"战略和保障能源安全的重要技术手段.中国石油高度关注CO2 资源化利用问题,在系统研究原始油藏、中高含水、高含水及特高含水油藏CO2 驱油机理与埋存潜力的基础上,研发了关键技术和工艺装备,形成了集CO2 捕集、输送、注入、采出、驱油、埋存、防腐等为主体的CCUS-EOR全产业链一体化技术体系,并率先在中国石油吉林油田开展了CO2 捕集埋存与提高采收率矿场实践.研究结果表明:①矿场试验证实CO2 驱油可提高采收率 20%以上,现已累计注入CO2 达 320×104 t;②矿场实践系统揭示了陆相低渗透油藏CO2 驱油与埋存规律,验证了CO2 捕集输送、注入采出、驱油埋存与循环利用全流程技术的适应性,实现了CCUS-EOR减排增效一体化.结论认为:①吉林油田建成了国内首个全产业链、全流程CO2 捕集、驱油、埋存与循环利用示范工程,实现了陆相沉积低渗透油藏CO2 驱油采收率的大幅提高和CO2 的安全埋存;②系统总结了吉林油田近年来在CCUS-EOR方面的最新研究进展和矿场实践认识,指明了油气田CCUS-EOR应用前景,并提出了以新质生产力推动相关企业产业化发展的具体建议.
CO2 capture,storage and enhanced oil recovery(CCUS-EOR)technology can greatly improve oil recovery factor and achieve effective CO2 storage,while realizing carbon emission reduction and oil recovery enhancement,so it is an important technical means to implement the"dual carbon"strategy and ensure energy security.PetroChina pays great attention to the issue of CO2 resource utilization.After systematically studying the CO2 flooding mechanism and storage potential in original,medium-high water cut,high water cut and extremely high water cut reservoirs,it develops key technologies and process equipment.And thus,a series of CCUS-EOR whole industry chain integrated technologies dominated by CO2 capture,transportation,injection,production,flooding,storage and anti-corrosion are developed.Besides,it takes the lead in the CCUS-EOR field practice in the Jilin Oilfield.And the following research results are obtained.First,the field test confirms that CO2 flooding can increase oil recovery factor by more than 20%,and a total of 320×104 t CO2 has been injected.Second,the field practice systematically reveals the CO2 flooding and storage laws in continental low-permeability reservoirs,verifies the adaptability of the whole process technology of CO2 capture and transportation,injection and production,flooding and storage,and recycling,and realizes the integration of CCUS-EOR emission reduction and efficiency improvement.In conclusion,domestic first demonstration engineering of CO2 capture,flooding,storage and recycling of the whole industrial chain and the whole process has been built in the Jilin Oilfield,and it has achieved significant oil recovery enhancement and safe CO2 storage in continental low-permeability reservoirs.What's more,this paper systematically summarizes the latest research progress and field practice understandings on CCUS-EOR in the Jilin Oilfield in recent years,predicts the application prospect of CCUS-EOR in oil and gas fields,and puts forward suggestions to promote the industrialization development of related enterprises with new quality productivity.
