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 aro-mati fractions in oil-sands and umderlying brown coal of coal-measures strata of the Baise basin inGuangxi 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 brow n coal. The conclusion of this paper provided a more dependable scientific basis for oilexploration in this area.
