【摘要】 CO₂过度排放所引起的温室效应已经对人类的生活造成了诸多不利影响。CO₂地质封存技术作为一项有效的CO₂处置技术,已经受到了越来越广泛的关注。研究了CO₂在模拟深部盐水层溶液中的溶解度及溶解度随埋存深度（800～2 800 m）的变化规律。结果表明,在800～1 700 m埋深范围内,CO₂溶解度随着盐水埋深的增加而减少;当埋深大于1 700 m时,CO₂溶解度则随着盐水埋深的增加而增加。CO₂溶解度随埋存深度的变化用方程进行了拟合,以此为基础预估了一定区域封存场地的CO₂封存量。更多还原

【Abstract】 The greenhouse effect caused by excessive CO₂ emissions has led to many adverse effects on human life. As an effective CO₂ disposal technology, CO₂ geological storage technology has aroused more and more attention. The solubility of CO₂ in simulated deep saline solution and its variation with burial depth（800～2 800 m）were studied. The results showed that, when the buried depth was in the range of 800～1 700 m, the solubility of CO₂ decreased with the increase of buried depth. When the buried depth was greater than 1 700 m, the solubility of CO₂ increased with the increase of saline depth. In addition, the change of CO₂ solubility with burial depth could be fitted by the equation. And based on this equation, the storage capacity of CO₂ in a certain area of storage site could be calculated.更多还原
