摘　　要：二氧化碳地质封存被认为是一项非常有潜力的CO2减排技术。其中对CO2地质储存能力的评估可作为某一国家、某一区域或某一具体储层是否适合CO2地质封存开展的判断依据之一。但目前的研究结果表明,对CO2地质储存容量的评估并不是一个简单而直接的过程。介绍了由碳封存领导人论坛(CSFL)提出的用于不可采煤层、油气储层和深部咸水含水层中CO2储存容量评估的方法。总结了影响CO2地质储存容量评估的主要因素,为我国在CO2地质封存领域研究的广泛合作提出了建议,有助于推动该技术在中国的深入开展。CO2 geological sequestration is one of the most promising methods for reducing anthropogenic CO2 emissions into the atmosphere. Therefore an assessment should be performed to determine whether there is sufficient CO2 storage capacity in a country, a region or a specific storage unit. Current study results indicate that CO2 storage estimation is not a simple and direct process. This paper introduced the method of CO2 storage capacity estimation in oil and gas reservoirs, deep saline aquifers, and coal seams presented by the CSFL Task Force. The main factors which may affect the estimation of CO2 geological storage capacity were presented, and some suggestions about the national collaborative program on the research of CO2 geological sequestration technology in China were put forward, which will be useful to the reduction of CO2 emissions in China.
