摘要(Abstract)：

CO_2在咸水层(盐沼池构造)中的封存是地质封存技术中封存量最大、最有前景的途径。总结了咸水层中封存CO_2机理及其在工程应用方面的主要进展。咸水层中CO_2地质封存的俘获机理比较复杂,是由一系列物理和地球化学的俘获机理共同作用的结果。论述了CO_2在咸水层地质封存的主要封存机理,如构造地层封存机理、水力学封存机理、束缚气封存机理、溶解封存机理和矿物化封存机理。现有的CO_2地质封存项目的顺利运行证明了其在咸水层中封存技术上的可行性。CCUS技术成功应用于咸水层仍有许多问题需要解决,如地质封存项目广泛分布在全球不同地质条件,需要不同的监测技术、法律监管问题及经济效益评估。
Storing CO_2 in saline formations is the largest and most promising method for geological storage. The mechanism of CO_2 storage in saline formations and the main development in engineering applications were summarized. The complex mechanism of CO_2 storage in saline formations is the result of a combination of physical and chemical capture mechanisms.The mechanism of structural formation storage, hydraulic storage mechanism, irreducible gas storage mechanism, dissolution storage mechanism and mineralization storage mechanism were reviewed. Current CO_2 geological storage projects prove feasibility of CO_2 sealing in saline formations. However, there are still many issues remain to be resolved, such as different detection techniques under different geological conditions of worldwide geological storage projects, and there are also different regulation issues, while their economics are required to be further understood for deploying CCUS in saline formations successfully.
