二氧化碳驱油( CO2-EOR)是一项通过向油层注入二氧化碳而提高石油采收率的技术,它能同时实现CO2的利用和封存,因此是CCUS的重要技术。近年来,随着离岸CO2封存需求的日益增大, CO2-EOR的应用正迅速从陆上扩展到海上。介绍了CO2-EOR的概念和适用条件,综述了国际上离岸CO2-EOR项目和技术,特别是“下一代”CO2-EOR技术的最新进展。通过与国外实例的对比和对盆地石油地质条件的分析,初步探讨了我国近海含油气盆地的CO2-EOR的潜力,认为渤海湾盆地(海域)和珠江口盆地分别具有非混相和混相CO2-EOR的潜力,有可能获得数亿吨石油的增产和实现数亿吨CO2的地下永久封存,需要尽快地开展进一步的研究和评估。

CO2-Enhanced Oil Recovery ( CO2-EOR) is a technique of enhancing oil recovery by injecting CO2 into oil reservoirs.It also realizes both CO2 utilization and CO2 storage and thus is an important technique in the CCUS chain.In recent decade the applica-tion of CO2-EOR is extended rapidly from inland to offshore, as a respond to the increasing demand for offshore CO2 storage.This paper briefed the concept and application conditions of CO2-EOR, and introduced worldwide projects and technical developments on offshore CO2-EOR, including the“Next Generation” CO2-EOR technology.A first-order preliminary review on the potential of CO2-EOR in offshore sedimentary basins off China was given for the first time based on comparison and analysis of petroleum geology of the basins.The Bohai Bay Basin ( offshore) and the Pearl River Mouth Basin are regarded as having the potential of non-miscible and miscible CO2-EOR, respectively.The CO2-EOR application in these basins might be able to bring several hundred million tons of in-cremental oil production and to store several hundred million tons of CO2 underground permanently.Further studies and evaluations are needed urgently.
