| 摘 要： | 通过研究三塘湖盆地马朗凹陷中上三叠统-中下侏罗统煤系烃源岩有机质类型(主要为Ⅲ型)及其演化程度(RO为0.5%~0.6%)和天然气特征(高含量烃类成份,高干燥系数,甲烷碳同位素较轻,乙烷和丙烷碳同位素较重),认为该凹陷天然气符合煤成生物-热催化过渡带气特征,并指出该套源岩从白垩纪开始进入煤成生物-热催化过渡带气生成阶段,其气源贡献可延续至第三纪末乃至更晚。

| Abstract: | Natural gas produced in Malang sag of Santanghu basin features high hydrocarbon content and high drying coefficient,with carbon isotope relatively light of methane and heavy of ethane and propane,which meets the characteristics of bio-thermocatalytic transitional zone gas through comprehensive analyses.The organic matter in middle to upper Triassic and middle to lower Jurassic coal measure source rock,which is the major source rock of natural gas in the basin,is type Ⅲ,and at its transitional zone gas evolu... |
