摘　　要：CO2地质封存技术虽是有效减排CO2和提高石油、天然气等能源采收率的技术手段,但目前该技术尚处于发展阶段。CO2地质封存工程可能诱发一些潜在的地质环境灾害风险,如浅层地表垂向差异变形、可能诱发的断层活化及地震事件、CO2逃逸导致淡水含水层的污染、CO2泄漏富集危害附近人类健康和局部生态系统等。本文分析了上述潜在地质环境灾害风险及灾害诱发模式,并从科学选址、风险评估、工程监管、监测预警、应急补救等角度提出了具体的防范措施和工程指导原则,对CO2地质封存技术的安全性评估和工程实施阶段的风险管理具有重要的现实意义。The CO2 geological storage technology has been considered as a promising way to effectively reduce CO2 emission and enhance the recovery rate of oil or gas.However,this technology is still in a developing stage and CO2 geological storage project may induce some potential geological and environmental risks,such as vertical deformation differences of the shallow surface,fault activation for triggering earthquakes,the pollution of freshwater aquifers,harms for human health and local ecosystems,and so on.The mentioned potential risks and its induction modes have been analyzed respectively.Then corresponding prevention principles and measures are suggested from such aspects as scientific site selection,risk assessment,project supervision,monitoring and pre-warning,and emergency reliefs.And this provides important practical implications for risk assessment and management of CO2 geological storage project.
