Based on the study on the reformation of Dawsonite sandstones with CO2 fluids at different temperature (100℃, 200℃ and 300℃) and different the CO2/H2O/sandstone systems in inclosed containers, it is suggested that the corrosion intensity of dawsonite sandstone will gradually be enhanced as the temperature increases.

不同温度（100℃，200℃和300℃）下CO2流体对含片钠铝石砂岩的改造作用研究显示：随着温度的升高，砂岩的溶蚀、溶解程度逐渐增强，样品中片钠铝石的稳定性逐渐减弱。

The solubility experiment for dawsonite indicated that under the stratigraphic condition, the temperature for the solution of dawsonite in 100~150℃,and the generation of some carbonate and other new mineral can occur after the reaction.

片钠铝石的溶解实验表明，地层条件下片钠铝石发生溶解的温度区间为100~150℃，且反应后有碳酸盐及其他矿物生成。

The solubility experiment for dawsonite indicated that under the stratigraphic condition, the temperature for the solution of dawsonite in 100-150℃,and the generation of some carbonate and other new mineral can occur after the reaction.

片钠铝石的溶解实验表明，地层条件下片钠铝石溶解的温度区间为100-150℃，且反应后有一些碳酸盐矿物和其他新矿物生成。

Based on the analysis of the mutual action between CO2 fluids and sandstone, it is found that the higher content of dawsonite is the main cause for poorer reservoir properties, and the dawsonite is formed later than other authigenic minerals and no erosion occurres after the pores filling, which are the basic factors resulting in poor reservoir properties.

分析CO2流体与砂岩的相互作用发现，片钠铝石含量较高是储层物性变差的直接原因，而片钠铝石生长时间晚于其它自生矿物且在充填孔隙后没有发生溶蚀是储层物性变差的根本原因。

The calculated δ13C values of CO2 gas being in equilibrium with dawsonite ranged from -8.7‰ to-6.9‰ and was in coincidence with the δ13C values ranging from -9.76‰to -5.74‰ of CO2 gas in Gudian carbonate dioxide gas field.

由于含片钠铝石砂岩与CO2气的分布都受控于深大断裂和玄武岩，CO2气和形成片钠铝石的CO2绝大部分属于幔源岩浆型。

However, dawsonite can be acted as trace mineral suggesting migration or accumulation of fluids with abundant carbon dioxide to whatever origin it belongs. In geological background, occurrence or enrichment of dawsonite indicates that migration or accumulation of carbon dioxide with large scale has happened.

然而，不论源于有机成因CO2气还是无机成因CO2气，片钠铝石均可作为富CO2流体运移或聚集的"示踪矿物"，地质过程中片钠铝石的出现或富集表明该区曾存在大量CO2运移或聚集。
