在西藏阿翁错盆地古近系牛堡组实测剖面的基础上,对烃源岩有机质丰度、有机质类型、有机质成熟度等方面进行研究,结果表明牛堡组烃源岩有机质丰度中等偏低,泥页岩和泥晶灰岩有机碳平均质量分数分别为0.26%和O.15%,泥页岩表现出较差烃源岩特征,泥晶灰岩则表现为中等烃源岩特征.泥页岩有机质类型以Ⅱ1型和Ⅱ2型为主,泥晶灰岩有机...
Based on the section of Paleogene Niubao Group in Awengcuo basin,the authors study on the organic matter abundance,organic matter type and organic matter maturity of the hydrocarbon source rocks.The result shows that the organic matter abundance of the hydrocarbon source rocks is below medium,and the average organic carbon contents of the clay shale and marlite are 0.26% and 0.15%,respectively.The clay shale demonstrates poor hydrocarbon source rock characteristics and its organic types areⅡ1-Ⅱ2.The marlite reaches the standard of moderate-good source rocks and its organic type is Ⅱ1.The organic matter maturity of the hydrocarbon source rocks from Paleogene Niubao Group is not high,almost in the stage of immaturity or low maturity.The whole assessment is that there are poor to medium source rocks in Niubao Group of Awengcuo basin.
