【摘要】 CO₂封存技术是一项具有大规模应用前景的CO₂处置技术,有望实现化石能源使用后CO₂的零排放。与之相关的CO₂在深部盐水层中的溶解度研究受到了广泛关注。本研究利用课题组自主建立的一种CO₂-盐溶液体系溶解度测定新方法探究地质封存条件下,超临界CO₂在深部盐水层中溶解度随深度（800m～2800m）变化的规律。实验结果表明:随着埋存深度的增加,CO₂在深部盐水层的溶解度呈先减小后增大的趋势。更多还原

【Abstract】 CO₂ sequestration technology is a disposal technology with large-scale application prospects,and it is expected to achieve zero emission of CO₂ after fossil energy use.Relatedly,the solu’bility of C02 in deep brine layer has received extensive attention.In this study,a new method for the determination of solubility in CO₂-salt solution system independently established by our group was used to investigate the variation of solubility of supercritical CO₂ in deep saline layer with increasig depth（800 m～2800 m）under geological storage conditions.The experimental results show that the solubility of CO₂ in the deep saline layer decreases first and then increases with the increase of the buried depth.更多还原
