| 摘 要： | 不同温度(100℃、150℃和200℃)地层水对含片钠铝石砂岩的改造作用研究显示,随着温度升高,砂岩的溶解程度逐渐增强,样品中片钠铝石的稳定性逐渐减弱。在片钠铝石溶解的同时,200℃时样品表面有高钠长石和绿泥石生成,且通过X-射线衍射分析发现,在150℃和200℃时有某种未知的碳酸盐矿物生成,生成量随温度升高而增大。100℃时片钠铝石的微弱溶解及150℃和200℃时碳酸盐矿物的生成表明,在地层条件下以片钠铝石等碳酸盐矿物形式捕获的CO2能够稳定存在。

| Abstract: | The reformation of sandstones with dawsonite and stratum water at different temperatures（100℃、 150℃ and 200℃） indicate that the solubility of sandstone enhanced and the stability of dawsonite decreased with the temperature increasing.At the same time of dawsonite dissolved,there are high albite and chlorite generated at 200℃.Analysis of X-ray diffraction indicates that there is an unknown carbonate mineral generated at 150℃ and 200℃,and the formation amount enhanced with temperature increasing.The weak solution of dawsonite at 100℃ and the formation of unknown carbonate mineral at 150℃ and 200℃ illuminate that the CO2 captured by carbonate can be stable in existence under strata. |
