Carbon capture, utilization, and storage (CCUS) technology has shown rapid development in recent years as an important to reduce carbon emissions, of which CO2 geological is part. Due the complexity storage, especially long period mineralization intensive studies have been conducted reveal mechanism storage. This review presents a comprehensive understanding its application prospects by introducing various experimental tools deepen characterization pore-scale core-scale changes during promote large-scale through geochemical simulations field-scale demonstrations. summarizes representative multiscale typical reservoirs. The main findings are follows: (1) For CO2–water–rock reactions, addition influence inherent inhomogeneity reservoir rocks (properties mineral components, etc.), environmental conditions (pH, temperature, pressure, etc.) strong on dissolution precipitation processes mineralized (2) sealing process accompanied complex evolution pore-permeability properties. stage causes increase pore space significantly improves fluid injection capacity, while reprecipitation problems such throat blockage, often affects safety sealing. (3) modeling approach, combined with laboratory work, allows for time-scale predictions. In addition, current implementation successful demonstration projects summarized use field engineering applications. Finally, directions future research proposed.
