摘要
本文介绍了源岩中轻烃的He抽提方法并直接与色谱联用分析其C_4～C_7轻烃。C_4～C_7轻烃在地球化学上有广泛的应用前景,文中以四川盆地两种不同来源的凝析油为例,讨论了利用这类烃来判断其母质来源、成熟度和气源对比。
An extracting method of light hydrocarbons in source rock has been introduced in this paper. The extracts can be directly analyzed with gas chromatography. C_4—C_7 light hydrocarbons have extensive application in geochemistry. Two different condensates from Sichuan basin being taken as an example, how to justify their source origin and maturity, and how to do gas source correlation by using C_4—C_7 light hydrocarbons have also been discussed in this paper.
