【摘要】 CO₂捕集、利用与埋存（CCUS）商业化的关键因素是通过工业CO₂排放源与油田间的源汇匹配,筛选出最具经济性的匹配方案。基于油藏驱油潜力和油田CO₂驱注气的阶段开发特点,以油田可承受CO₂极限成本为约束条件,CCUS商业化项目的总成本现值最小为优化目标,建立了工业CO₂排放源与具有效益开发潜力油藏的CCUS源汇匹配评价流程和相关指标计算方法。并以我国东部地区某油田及附近碳源为例,筛选出可承受CO₂极限成本大于150元/t的油田区块,将CCUS全生命周期划分为6个阶段,完成燃煤电厂（碳源地）与油田区块间管道布局和CO₂注入井的接替（分阶段）注采规划,并发现当油价高于70美元/桶时,油田区块的平均可承受CO₂极限成本接近该源汇匹配下的全生命周期CO₂平均供给成本。更多还原

【Abstract】 The key factor for CO₂ capture, utilization and storage（CCUS） commercialization is to screen the most economical matching scheme through source-sink matching between industrial emission source and oil field. In this paper, based on the flooding potential of oil reservoirs and stage development characteristics of CO₂ flooding and gas injection of oil fields, a CCUS source-sink matching evaluation process and calculation method of relevant indicators were developed under the constraint of the affordable CO₂ limit cost of the targeted oil fields, and with the minimum total present cost value of the CCUS commercial project as the optimization target. In addition, this paper took a certain oil-field and its nearby carbon sources in the eastern region of China for instance, screened the oil blocks whose affordable CO₂ limit cost was higher than RMB 150/t, and divided the whole lifecycle of CCUS into 6 stages, completed the distribution of pipelines between coal-fired power plants（carbon source） and oil blocks and the replacement（staged） injection-production planning for CO₂ injection wells, and the results showed that when international crude oil price was above $70/barrel, the average affordable CO₂ limit cost was close to the average CO₂ supply cost during the whole lifecycle under this source-sink matching.更多还原
