摘　　要：将CO_(2)捕集、利用与封存(CCUS)技术与提高原油采收率(EOR)技术相结合,将捕集的CO_(2)注入地下驱油,在提高采收率的同时实现碳封存。CCUS-EOR项目的完整流程包括捕集压缩、运输、驱油、回注等多个环节。本文将CCUS-EOR全流程视为一个整体,通过剖析CO_(2)驱与常规水驱开发成本构成差异,建立适宜的CCUS-EOR项目全成本经济评价体系,确定捕集成本、运输成本、驱油成本的取值依据,推导出考虑碳减排收益的盈亏平衡模型,满足CCUS-EOR项目快速评价、辅助决策需求。Combining CO_(2) capture,utilization,and storage(CCUS)technology with enhanced oil recovery(EOR)technology,the captured CO_(2) is injected into underground for oil displacement,achieving carbon sequestration while improving oil recovery.The complete process of the CCUS-EOR project includes multiple stages such as capture and compression,transportation,oil displacement,and recovery.This article regards the entire CCUS-EOR process as a whole,analyzes the differences in cost composition between CO_(2) flooding and conventional water flooding development,establishes a suitable CCUS-EOR project full cost economic evaluation system,determines the basis for the values of capture cost,transportation cost,oil recovery cost,and derives a break even model considering carbon emission reduction benefits,meeting the needs of rapid evaluation and auxiliary decision-making for CCUS-EOR projects.
