CO2咸水层封存关键参数及其实验表征技术研究进展
摘要:CO2咸水层封存作为碳捕集、利用与封存(carbon capture, utilization and storage,CCUS)技术的重要一环,是实现碳中和目标的有效手段,完善咸水层封存机理研究方案对于准确评估CO2咸水层封存潜力具有重要意义。讨论了CO2咸水层封存机理,总结了实验过程中常用的表征技术,论述了不同参数对咸水层封存的影响,并对该技术的未来发展做出了展望。针对不同的封存机理研究,咸水层封存的表征技术主要包括储层岩石表征、岩心驱替实验、溶解性实验、矿化反应实验等。CO2咸水层封存潜力受残余水饱和度、残余气饱和度、溶解度和盐析程度等多个参数的影响,因此选用合适的表征技术确定相关参数对于确保封存潜力评估的准确性至关重要。此外,开展全过程封存机理分析和海上咸水层封存项目研究是该技术未来研究的重要方向。
Abstract: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.
