The risk potential matrix method can be used as a reference for the optimization of the traditional risk matrix in geological CO₂ storage. This study used monitoring data for environmentally sensitive receptors in the Jilin Oilfield CO₂-enhanced oil recovery (CO₂-EOR) Hei-79 block in conjunction with a hazard event store to create an updated risk assessment of CO₂ capture, use, and storage (CCUS) as a guide for risk management. The assessment built upon the overall project operation status to evaluate six and five sub-categories of hazard and sensitivity, respectively. The environmental sensitivity threshold integrated ecosystems and secondary geological disasters to amplify potential risks. The results of the risk assessment of the CO₂-EOR Hei-79 block in the Jilin Oilfield showed that despite an overall risk level of Ⅱ, the hazard level resulted in an unacceptable increase in overall risk. Formations are usually stimulated by fracturing in Jilin Oilfield, particularly for oil and gas production. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd.

使用风险分解结构方法对CCUS项目进行风险评估——以吉林油田CO2-EOR Hei-79区块为例

潜在风险矩阵法可作为地质CO ₂封存中传统风险矩阵优化的参考。本研究使用吉林油田 CO ₂提高采收率 (CO ₂ -EOR) Hei-79 区块中环境敏感受体的监测数据，结合灾害事件库，对 CO ₂进行更新的风险评估捕获、使用和存储 (CCUS) 作为风险管理指南。评估以项目整体运营状况为基础，分别评估了六个和五个子类别的危害和敏感性。环境敏感性阈值综合生态系统和次生地质灾害以放大潜在风险。吉林油田CO ₂ -EOR Hei-79区块风险评估结果表明，尽管总体风险等级为Ⅱ级，但危害程度导致总体风险增加不可接受。吉林油田通常通过压裂对地层进行增产，特别是在油气生产方面。© 2021 化学工业协会和 John Wiley & Sons, Ltd.
