本文综述了咸水层中二氧化碳储存的关键领域。在几个潜在的二氧化碳地质储存地点中，盐水层提供最高的储存潜力，并且在世界范围内相对常见。二氧化碳在含盐地层中的地质储存是通过各种物理和化学捕集机制实现的。当二氧化碳被注入地下时，它首先被主要的捕获机制捕获，这些捕获机制是盖层下方的静态和流体动力学捕获。次级捕集机制，溶解度，矿物和残留物捕集，比初级捕集机制慢得多，并且具有长得多的操作时间。由于盐岩层在不同时间尺度下的特征描述、异质性和圈闭机制，有关盐岩层储集能力的知识具有高度不确定性，这对建立可靠的储集能力估计方法提出了巨大挑战。S的潜在成本
This paper reviews key areas of carbon dioxide storage in saline aquifers. Among several potential geological carbon dioxide storage sites, saline aquifers offer the highest storage potential capacity and are relatively common worldwide. Geological storage of carbon dioxide in saline formations is achieved through various physical and chemical trapping mechanisms. When carbon dioxide is injected in the subsurface, it is first trapped by primary trapping mechanisms, which are static and hydrodynamic trapping below the cap rock. The secondary trapping mechanisms, solubility, mineral and residual trapping, are much slower and have a much longer timeframe for operating than primary trapping mechanisms. Knowledge regarding storage capacity in saline formations is highly uncertain due to their poor characterisation, heterogeneity and trapping mechanisms operating at different timeframe scales, which pose a huge challenge to establish a reliable methodology for storage capacity estimates. The potential cost of s...
