| 摘 要： | 通过对准噶尔盆地西北缘红旗坝地区钻遇的二叠系烃源岩岩芯和原油样品进行地球化学分析，包括族组分、同位素 和生物标志物等，结果表明，准噶尔盆地西北缘红旗坝地区二叠系泥岩有机质丰度低，类型较差，红旗坝及其邻近地区的 原油与玛湖凹陷风城组烃源岩在三环萜烷C20，C21 和C23 分布趋势、Pr/Ph 和碳同位素等存在良好对应关系，因此红旗坝地区 原油主要来自玛湖凹陷风城组烃源岩的贡献。 |

| Abstract: | Analyses of geochemical characteristics of oil fractions,C-isotope and biological markers of well cores and crude oil from the Hongqiba area in the northwestern margin of Junggar Basin reveal that the source rock has low abundance in organic matter and poor kerogen.Oils from Hongqiba and its adjacent areas show a certain degree of correlations with the source rocks of the Fengcheng Formation in the Mahu sag with regard to the distribution of C 20,C 21,C 23 tricyclic diterpanes,Pr/Ph,and carbon isotope.Therefore,we suggest that oils mainly originated from the Fengcheng Formation of the Mahu sag. |
| Keywords: | source rock evaluation oil-source correlation Hongqiba area Junggar Basin |
