underlying stratum meaning in Chinese
下伏地层
Examples
- The static headspace gas analytical technique is mainly devoted to the analysis of physically - adsorbed and dissolved light hydrocarbons whose composition and content can directly reflect oil and gas information of the underlying strata
摘要静态顶空气分析技术主要是物理吸附轻烃及溶解轻烃，其组成和含量上的特徵可直接反映对应地层及下伏地层的含油气信息。 - All sha - 1 and sha - 2 segments are characterized by over - pressure , indicating that the preservation conditions within sha - 1 and sha - 2 segments are good and hydrocarbon accumulations within them are likely formed and contained . since over - pressure strata can prevent hydrocarbon in the underlying strata from dispersing , they can be considered as effective seals
沙一、二段具有整体明显的相对超压特征，这一方面表明沙一、二段的保存条件比较好，有利于沙一、二段油气藏的形成与保存；另一方面，超压层的形成可以有效阻止下覆油气层的散失。
