二氧化碳地质封存中的储存容量评估：问题和研究进展

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 Storage Capacity Estimation in Geological Sequestration: Issus and Research Progress

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 CO₂storage 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.
