摘　　要：对内蒙古扎鲁特地区鲁D1井上二叠统林西组（P3l）的发育特征及暗色泥岩的有机质丰度、类型和成熟度进行了研究,结果表明,P3l暗色泥岩发育（厚度达到775m）,总有机碳质量分数ω（TOC）分布在0.12％～1.35％,平均值为0.58％,达到了中等烃源岩标准；应用Pr/n-C17与Ph/n-C18的相关关系及C27、C28、C29甾烷（ααα-20R）三者的相对含量,判断其有机质类型为Ⅱ型；镜质组反射率与伊利石结晶度分析表明烃源岩演化达到了过成熟阶段.综合评价认为,P3l是潜在的烃源岩层位,具备较好的生气潜力.Based on the research of distribution growing characteristics,organic matter abundance,type and maturity index of the dark mudstones of Well Lu D1of Linxi Formation(late Permian)(P3 l)in Zhalute Region of Inner Mongolia, the result indicated that dark mudstones were developed in the area,its thickness was 775m.Total organic carbon(w(TOC))content was ranged from 0.12to 1.35,its average value was 0.58weight percentage.It met the standard of medium organic matter abundance.According to the relationship and relative contents between the ratios of Pr/n-C17, Ph/n-C18 and the steranes C27,C28,C29,the organic matter type was judged as TypeⅡ.Vitrinite reflectance and illite crystallinity analyses showed that the source rock evolution reached at matured stage.The evaluation indicates that Linxi Formation is a zone of potential source rocks,it has good potential force of gas generation.
