本文运用热解气相色谱（ＰＹ－ＧＣ）技术探讨了我国一些含煤油气盆地中煤系源岩热解产物的组成特征及意义。研究表明，不同盆地煤系源岩热解产物的差异主要表现在Ｃ正构烷烃＋正构烯烃含量和芳环化合物的组成上，利用热解产物Ｃ１—Ｃ５、Ｃ６—Ｃ１４正构烷烃＋正构烯烃和Ｃ正构烷烃＋正构烯烃三个端元组分的相对含量可有效地判识煤系地层源岩有机质的产烃类型，研究表明ＰＹ－ＧＣ技术是一种值得推广的煤成烃评价方法。
In this paper, pyrolysis gas chromatography (PY-GC) was used to explore the composition and significance of pyrolysis products of coal-bearing source rocks in some coal-bearing oil and gas basins in China. The results show that the pyrolysis products of coal-derived source rocks in different basins are mainly characterized by the content of C-n-alkanes + n-olefins and the composition of aromatic compounds. The pyrolysis products C1-C5 and C6-C14 n-alkanes + The relative content of the three terminal components of the constituent olefins and C n-alkanes + n-olefins can effectively identify the types of hydrocarbons produced by the organic matter in the source rocks of coal measures. Studies have shown that PY-GC is a promising coal Hydrocarbon evaluation method.
