摘要

石油有机地球化学研究中,凝析油的成因热演化程度及母质来源的探讨,需要更为详细的凝析油组成数据。随着毛细管色谱技术的快速发展,为石油烃类复杂混合物分离提供了可行的途径。本方法主要采用高效石英毛细柱,OV—101固定相,选择适当的实验条件,较好地分离了凝析油全烃和轻油镏份正辛烷以前的单体烃63个组份,同时使用程序升温及Van Den Dool保留指数值进行轻油单体烃谱峰的定性分析。

Abstract

Fused capillary column coated with OV-101 is used in this new method. The distribution of hydrocarbons in some condesates samples has been studied with 15m column. For the prefractionization (below 130℃)of condesates, the seperation was carried out on a 50m column. More than 63 peaks (up to NC8) are identied with their corresponding Van Den Dool indices. The analytical conditions are listed. The results and their geochemical applications have been discussed.
