摘要
从沉积特征、岩性分布以及烃源岩厚度展布特征入手,对四川盆地下三叠统飞仙关组的烃源岩在平面上的分布进行了描述,并结合有机质丰度、有机质类型和有机质成熟度等烃源岩评价指标,对飞仙关组烃源岩特征进行了分析,研究表明:下三叠统飞仙关组生烃条件较差,但在川东部分地区具有局部生烃能力。
The planar distribution of source rock in Lower Triassic Feixianguan Formation of Sichuan Basin was described by the deposition,lithologic distribution and thickness of source rock.In addition,the source-rock characteristics were also analyzed by some source-rock evaluation index of organic-matter abundance,type and maturity.Results show that the hydrocarbon-generated condition of Lower Triassic Feixianguan Formation is poor where there is a certain hydrocarbon-generated capability in part areas of East Sichuan Basin.
