Geological storage of CO is a promising technique to mitigate anthropogenic CO emissions. The effectiveness of CO storage in the subsurface formations relies on various trapping mechanisms that immobilize the injected CO. Among these mechanisms, residual trapping has been identified as a critical factor, closely associated with residual CO saturation. The extent of residual CO saturation is strongly influenced by the petrophysical, physicochemical and hydrodynamic properties of CO/fluid/rock systems and operational conditions, thereby governing the overall residual trapping efficiency.

二氧化碳地质封存地下系统的残余捕集能力：测量技术、影响因素荟萃分析和未来展望

二氧化碳地质封存是减少人为二氧化碳排放的一项有前途的技术。地下地层中二氧化碳封存的有效性依赖于固定注入二氧化碳的各种捕集机制。在这些机制中，残余捕集已被认为是一个关键因素，与残余二氧化碳饱和度密切相关。残余二氧化碳饱和度受到二氧化碳/流体/岩石系统的岩石物理、物理化学和流体动力学特性以及操作条件的强烈影响，从而控制总体残余捕集效率。
