| 摘 要： | 为了更加准确地预测和评价珠江口盆地惠州凹陷古近系油气资源潜力，精细划分了该凹陷油气汇聚单元和成藏体系，并利用层序地层学和地球化学相结合的方法，分析了该凹陷古近系始新统一下渐新统恩平组和始新统文昌组6个三级层序烃源岩有机质丰度、有机质类型、生烃潜力大小和生物标志物组合特征，指出文昌组SQ2层序地层中一深湖相泥岩是主力烃源岩，恩平组SQ5和SQ6层序地层沼泽相、河流三角洲相和浅湖相煤系烃源岩是重要烃慊岩。

| Abstract: | The organic abundance, organic types, hydrocarbon-generating potential and biomarker composite in the six three-class sequence Palegene source rocks from the Huizhou depression are investigated by methods of sequence strata and geochemistry, in order to exactly predict and evaluate the petroleum and gas generation in Pearl River Mouth basin, and subtly classify petroleum systems. The middle-deep lacustrine mudstone in the SQ2 member of Wenchang Formation in Eocene is main source rock, and the swamp and fluvio-deltaic and coal measure in the members of SQ5 and SQ6 of Enping Formation in Oligocene is an important source rock. |
