通过对原油样品的族组成、饱和烃色谱、质谱分析，详细描述了鄂尔多斯盆地南部富县地区延长组主要含油层长6段和长2段原油地球化学特征，进行了油-油对比研究。研究结果表明，富县地区延长组长6段和长2段含油层原油地球化学特征基本相近，原油为成熟石蜡型原油，有机母质来源于细菌和藻类，形成还原陆相淡水湖泊环境，应来源于本区延长组长7段烃源岩。

Based on the composition of crude oil samples, chromatographic analysis and mass spectrometry of saturated hydrocarbons, the geochemical characteristics of crude oil and the oil-oil correlation of the main reservoir of Chang 6 member and Chang 2 member of the Yanchang Formation in Fu-xian area were discussed. The results showed that the geochemical characteristics of crude oil were similar in two areas. The crude oil probably derived from the chang7 of Yanchang Formation source rock.
