| 摘 要： | 二连盆地由５０多个断陷组成，主要的烃源岩是下白垩统巴彦花群，从烃源岩的干酪根及热解等资料分析来看，生油岩母质类型以Ⅱ１－Ⅱ２型为主，是典型的混合型生油岩；而烃源岩的可溶性有机质鉴定结果发现含有大量的高等植物标志化合物，说明早白垩世断陷湖泊有机质主要来源于高等植物，分析认为这一现象是由于高等植物“腐泥化”的结果，并通过有机相综合分析，明确了断陷群不同相带的生烃潜力及成油特征，并指明断陷群的勘探前景．

| Abstract: | Erlian Basin consists of above fifity downchasms.Its hydrocarbon source rock is mainly lower Cretaceous Bayanhua group.By the analyses of kerogen and its pyrolysis data of hydrocarbon source rock,it is konwn that the parent rock of the oil source rock is mainly Ⅱ 1 Ⅱ 2 types of kerogen,which is a typical mixed oil source rock.A large quantity of labeled compound from high rank flora is found in the soluble organic matter of the hydrocarbon source rock,which shows that the organic matter is the result of the saprofication of the high rank flora.The genetic potential and genetic feature of the different facies tracts of the downchasm group and their exploration prospects are revealed by the synthetical analysis of organic facies. |
