摘要
通过对塔里木盆地寒武－奥陶系和石炭系干酪根热解产物的研究，讨论了以下问题：①寒武－奥陶系干酪根的母源特征；②寒武－奥陶系干酪根生成海相中含蜡原油的可能性；③干酪根热解产物生物标志化合物的特征及其在油源对比应用中的意义。研究结果表明，细菌、蓝藻细菌（Ｃｙａｎｏｂａｃｔｅｒｉａ）是塔里木盆地寒武－奥陶系有机质的重要组成成分，在较高的成熟度条件下，这种菌藻母质可以生成中含蜡原油。
This paper gives a study on the pyrolytic products of kerogen in Cambrian-Ordovician and Carboniferous in Tarim basin, and the following items are discussed:① the features of source of Cambrian-Ordovican kero gens; ②the probability for the generation of medium waxy marine oils from Cambrian-Ordovician;③ the features of biomarkers in the pyrolytic products of kerogens and their application to oil-source correlation. We concluded that the organic matter in Cambrian-Ordovician-Bacteria and Cyanabacteria which can gen erate medium waxy oils and are the main source of marine oils in Tarim basin.
