大兴安岭南部内蒙古林西地区发育有晚古生代地层，其中上二叠统林西组发育巨厚层暗色泥岩，具有潜在的生油、储油环境。通过有机岩石学、有机地球化学相结合的方法，对内蒙古林西地区上二叠统林西组泥岩显微组分、有机质丰度、有机质类型以及有机质成熟度进行特征研究。有机碳含量测定结果平均0.61％，表明有机质丰度较高，属于较好烃源岩，具有较强的生烃能力，但由于其有机质类型主要为Ⅲ型，且处于高成熟-过成熟的高变质演化阶段，生烃应主要以生气为主。

The stratum of Late Palaeozoic exist in Linxi region , Inner Mongolia of Greater Hinggan southern ar-ea.Dark and thick mudstone layer with potential conditions for hydrocarbon generation and reservoir in Linxi formation of Upper Permian develop well in this region.The feature of maceral , abundance , type and maturity of organic matter of Linxi formation is studied with the method of combining organic petrology and organic geo-chemistry together.The average level of determination of the organic carbon percentage is 0.61%, which shows abundance of organic matter in the mudstone is relatively high.Therefore , the mudstone of Linxi Forma-tion is better hydrocarbon source rock with highly producing ability of hydrocarbons.While the generation abil-ity of hydrocarbon in Linxi Formation mudstone should be gas because of the organic matter type of the mud -stone is mainly type Ⅲand the Organic matter maturity of the mudstone mainly belongs to the high mature to over mature evolutionary stage.
