| 摘 要： | 对济源盆地谭庄组油页岩的沉积环境进行了介绍,对大量样品进行了含油率测定,表明含油率平均只有0.3%,最高的有1.68%,远远达不到油页岩的边界品位(3.5%).从地球化学角度对油页岩进行研究发现:有机质丰度高,其中有机碳含量平均达到4.68%,最高可达到11.63%;有机质类型多属于腐殖-腐泥(ⅡA)和腐泥-腐殖(ⅡB)型,是介于生油和生气之间的过渡类型;有机质成熟度处于低成熟-高成熟阶段之间,具有很大的生烃潜力.

| Abstract: | The paper briefly discussed sedimentary environment of the oil shale in Tanzhuang Formation,Jiyuan Basin,and determinated the average ratio of oil in samples is only 0.3%,the largest value is 1.68% much less than the cut-off grade(3.5%).But from geochemical research the abundance of organic matter is wide,organic carbon content average is 4.68%,the maximum value is 11.63%,and the type of organic matter mostly are ⅡA and ⅡB,which are the middle type of generation of oil and gas.The maturity of the organic matter is between lower and high stage,which has high generation potential of Hydrocarbon. |
