摘要
CCUS-EOR技术不仅是我国实现“碳达峰、碳中和”的重要举措,也是低渗透油田大幅度提高采收率的战略性接替技术。确保CO_(2)驱油集输系统生产稳定性,是加大CCUS-EOR推广应用力度的重要保障。针对CO_(2)驱采出流体气液比高于水驱、化学驱等开发方式,且采出气中高含CO_(2),导致集输系统运行出现气段塞等不稳定的问题以及对典型工程实例分析,分析国内外CO_(2)驱集输系统确保生产稳定性采取的典型做法,提出今后开展CO_(2)驱油集输系统生产稳定性保障措施的几点建议。
The CCUS-EOR technology is not only an important measure to achieve"carbon peak and carbon neutrality"in China,but also a strategic replacement technology to significantly improve oil recovery in low-permeability oilfields.Ensuring the production stability of CO_(2) flooding oil gathering and transportation system is an important guarantee for increasing the promotion and application of CCUS-EOR.In view of the fact that the gas-to-liquid ratio of CO_(2) flooding recovery fluids is higher than that of water-driven and chemical-driven development methods,and that CO_(2) is contained in the recovery gas,there are unstable problems and typical engineering examples that are easy to occur in the operation of the gathering system,this paper is analyzed the typical practices taken by the CO_(2) flooding gathering and transportation system at home and abroad to ensure the production stability,and puts forward several suggestions for developing the production stability guarantee measures of the CO_(2) flooding oil gathering and transportation system in the future.
