As an important part of carbon capture, utilization and storage(CCUS) technology, CO2 sequestration in saline aquifers is an effective means to achieve the goal of carbon neutralization. Improving the research scheme of CO2 sequestration mechanism in saline aquifers is of great significance to accurately evaluate the storage potential. The storage mechanism of CO2 sequestration in saline aquifers was discussed, the commonly used characterization techniques were summarized, the effects of different parameters on sequestration in saline aquifers were discussed, and the future development of this technology was prospected. According to the study of different storage mechanisms, the characterization technology of sequestration in saline aquifers mainly includes reservoir rock characterization, core flooding experiment, solubility experiment, mineralization reaction experiment and so on. The storage potential of CO2 sequestration in saline aquifers is affected by many parameters, such as the residual water saturation, residual gas saturation, solubility and salt precipitation. Therefore, it is very important to select appropriate characterization techniques to determine the relevant parameters to ensure the accuracy of storage potential evaluation. In addition, the analysis of the whole process storage mechanism and the research of marine CO2 sequestration in saline aquifers project are the important research direction of this technology in the future. |
