| 摘 要： | 本文通过对广西百色盆地煤系地层油砂及下层褐煤中饱和烃、芳烃生物标志物鉴定及进行对比分析，发现两者生物标志物分布特征极为相似。结合有机岩石学研究成果，作者认为油砂中的烃类大部分就是源于这种褐煤。本文通过对百色盆地煤系地层油砂生物标志物进行研究，以对本地区煤系地层油气勘探提供更可靠的科学依据。

| Abstract: | In this paper, the identification and comparative analysis on the biomarkers of the aliphatic and aromati fractions in oil sands and umderlying brown coal of coal measures strata of the Baise basin in Guangxi were studied, their biomarker distributive characteristics are extremely similar. Combimed with organic petrological study, it was beieved that hydrocarbons in oil sands come mainly from the brown coal. The conclusion of this paper provided a more dependable scientific basis for oilexploration in this area. |
