结果表明，玄武岩盖层下空气的CO2浓度具有双向变化梯度与明显的季节变化，而第三系盖层下随深度递减且季节变化不显著；

The results demonstrate that CO 2 concentration in air under the basaltic cover shows obvious seasonal variation and a two way variation gradient , while in air under the Tertiary cover , the concentration decreases with depth without obvious seasonal variations .

CSWI既可以反映泥质岩盖层本身特征对水溶相天然气封闭能力的影响，又可以反映地层水特征对水溶相天然气封闭能力的影响。

CSWI can reflect not only the influence of the characteristics of mudstone caprock itself on its seal ability to gas in water-dissolving phase , but also the influence from the characteristics of the formation water to the seal ability of mudstone caprock to gas in water-dissolving phase .
