| 摘 要： | 扎鲁特盆地上二叠统林西组发育一套分布范围广、厚度大的泥岩,是潜在的烃源岩层系.采用有机质丰度、类型、来源和成熟度指标对盆地发育的林西组露头样品进行了分析.测试结果显示:林西组泥岩有机质丰度中等—较好,属于中等烃源岩;有机质类型均为Ⅲ型;有机质最大热解温度T max在363581℃之间,镜质组反射率(Ro)分布在1.38%581℃之间,镜质组反射率(Ro)分布在1.38%2.8%,均值为2.01%,二者表明林西组泥岩处于高成熟到过成熟阶段.研究表明:林西组泥岩为较好烃源岩,具有一定的生气潜力.

| Abstract: | A series of thick mudstone of the Upper Permian Linxi Formation,which is a potential layer for hydrocarbon source rock,is widely distributed in the Jarud Basin.Indexes such as organic abundance,type,source and maturity are used to analyze the outcrop samples from Linxi Formation.The testing result shows that the organic abundance of the mudstone is medium to relative-good degree,belonging to medium grade of hydrocarbon source rock,with organic type Ⅲ.The maximum pyrolysis temperature of organic matter varies from 363℃ to 581 ℃.The vitirnite reflectance is distributed from 1.38% to 2.8% with average of 2.01%.The data suggest that the mudstone of Linxi Formation be in high-and overmature stage.The research reveals that the mudstone of Linxi Formation is a kind of favorable hydrocarbon source rock with good exploration prospect for gas resource. |
