静态顶空气分析技术在油气化探中的应用

THE APPLICATION OF THE STATIC HEADSPACE GAS ANALYTICAL TECHNIQUE TO OIL-GAS GEOCHEMICAL EXPLORATION

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征可直接反映对应地层及下伏地层的含油气信息。运用于地表化探,预测与判断油气层的横向剖面位置与性质;运用于井中化探,利用轻烃的组成和含量上的特征可准确预测与判断油气层的纵向剖面位置与性质。

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. When used to surface geochemical exploration,it can predict and judge the position and properties of the transverse profile of the oilgas horizon;when employed to borehole geochemical exploration,it can accurately predict and judge the position and properties of the longitudinal profile of the oilgas horizon based on the composition and content of the light hydrocarbon.
