| 摘 要： | 对华北地区石炭－二叠系、下第三系、中上元古界沉积物和油样的低环萜烷参数用因子分析方法进行油源对比，表明石炭－二叠系部分样品与该区轻质油的关系密切。进一步分析这套地层的有机地球化学特征后，提出壳质组含量和成熟度是决定石炭－二叠系能否生成轻质油的主要因素，并提出该区煤系地层生成轻质油的成熟度下限是镜质组反射率Ｒ０为１．１％。

| Abstract: | The relationship between source rocks of Permian-Carboniferous, Lower Tertiary,Middle and Upper Proterozoic group and light crudes were studied by factor analysis of low-ring terpanes of the samples in Hebei Oil Field. The results indicate that some Permian-Carboniferous samples have good relationship with light crudes. Further study on their composition of organic matter shows that the content of exinite and maturation (vitrinite Ro<1.1 %)is two main factors for light crudes generation from coal measure strata. |
