二氧化碳封存技术研究进展

CO₂作为最重要的温室气体越来越受关注,而CCS技术因在大规模减少温室气体排放方面的潜力也受到广泛重视。在广泛搜集国内外有关CCS技术相关资料的基础上,详细介绍了最新的CCS技术现状,列出了国内外最新CCS工程案例,讨论了地质封存、CO₂-EOR、CO₂-ECBM技术的内涵及研究进展,对深部咸水层、枯竭油(气)田、玄武岩含水层、CO₂-EOR及CO₂-ECBM封存技术选型、CO₂泄露、储存容量和可注入性、试验与模拟技术以及选址与风险评估等研究现状进行了讨论并指出了下一步的研究重点。最后,对中国的CCS技术发展进行了展望。

Review of the Technology for Sequestration of Carbon Dioxide

Carbon dioxide, the most important greenhouse gas responsible for climate change, is gaining more and more attention. People start to focus on Carbon Dioxide Capture and Storage (CCS) which can reduce greenhouse gas emissions on a large scale. Based on collecting comprehensive information about geologic sequestration of CO₂ both at home and abroad, this review introduces the present status of CCS and cites the latest CCS projects both at home and abroad. Furthermore, this review discusses the definition and review of geologic sequestration, CO₂ Enhanced Oil Recovery (CO₂-EOR) and CO₂ Enhanced Coal Bed Methane (CO₂-ECBM). The technologies of deep saline reservoir, depleted oil (gas) reservoir, basalt aquifers, CO₂-EOR and CO₂-ECBM choice, CO₂ seepage, capacity of reservoir and ability of injection, experiment and numerical modeling, site selection and risk evaluation are also discussed and the authors point out the study emphasis for the further research. At last, this review has an overlook on the study of CCS in China.
