摘要
顶空气所分析的主要是物理吸附轻烃及溶解轻烃,其组成和含量上的特征可直接反映对应地层及下伏地层的含油气信息。应用于地表天然气化探,可预测与判断油气层的横向剖面位置;应用于井中天然气化探,可根据顶空气的轻烃组成和含量上的特征,准确预测与判断天然气层的纵向剖面位置与性质。
Headspace gas technology can be used to analyze physically absorbed and dissolved light hydrocarbons whose composition and content can directly reflect oil and gas information of the underlying strata. When used to surface geochemical exploration, it can predict and judge the position and properties of the transverse profile of the oil-gas zone. It can accurately predict and judge the position and properties of the longitudinal profile when employed to borehole geochemical exploration.
