    新疆伊宁盆地石炭系阿克沙克组烃源岩特征

    Characteristics of Carboniferous source rocks in the Yi'ning basin, Xinjiang

    • 摘要: 从纵向展布、有机质丰度、类型及热演化特征等方面分析了新疆伊宁盆地下石炭统阿克沙克组烃源岩特征。石炭系阿克沙克组烃源岩分布集中,厚度较大,阿克沙克剖面累计厚度达202.1m,总有机碳(TOC)含量平均为1.19%;干酪根类型为Ⅱ1型;镜质体反射率(Ro)平均为1.56%,表明干酪根演化进入高成熟阶段。综合评价认为,下石炭统阿克沙克组具有较好的生烃条件,伊宁盆地石炭系具有良好的油气资源前景。

       

      Abstract: The characteristics of source rocks were analyzed for Lower Carboniferous Akeshake Formation in Yi'ning basin, Xinjiang, in the aspects of vertical distribution, richness of organic matter, organic matter type and thermal evolution of organic matter. The source rock of Akeshake Formation exhibits centralized distribution with a great thickness, and its gross thickness is 202.1m, total organic carbon content (TOC) is 1.19%, and kerogen type is Ⅱ1 with average vitrinite reflectance (Ro) being 1.56%. These data show that the kerogene has evolved into high mature stage, and the lower Carboniferous Akeshake Formation has good hydrocarbon generation conditions. There are good prospects for oil and gas exploration in Yi'ning basin.
