煤和陆源有机质生油岩与海相、湖相腐泥型生油岩组成了地质体中的三大类型生油岩。其特点是：生油岩中有机质以高等植物占绝对优势，以Ⅲ型干酪根为主；有机质由生油富氢组分（包括壳质组分、腐泥组分和超微类脂体）和不生油贫氢组分组成。前者的数量决定着这种生油岩的生油潜力。由于煤和陆源有机质烃源岩在组成和结构上的复杂性，必须采取以荧光显微镜为主，并结合反光、透射电子显微镜分析技术，进行分层次（深入到显微组分、亚显微组分、微显微组分）的研究，才能准确评价此类生油岩。新疆侏罗系煤系烃源岩富氢组分中以镜质组（其中含有一定数量的超微类脂体）占绝对优势，暗色泥岩中相对富含类脂体组分，其生油潜力不容忽视。
Coal and terrigenous organic matter source rocks and marine facies and lacustrine sapropelic source rocks constitute the three major types of source rocks in the geological body. Its characteristics are: the organic matter in the oil-bearing rocks is dominated by higher plants, with Type III kerogen as the dominant species; and the organic matter is mainly composed of hydrogen-rich components derived from oil (including the chitin component, the sapropel component and the ultramicro lipid) And no oil depleted hydrogen components. The former number determines the potential of this source rock. Due to the compositional and structural complexity of coal and terrigenous organic source rocks, it is necessary to adopt fluorescence microscopy as the main method and combine with reflective and transmission electron microscopy techniques to carry out stratification (deep into microstructure, sub-microstructure Points, micro-micro-component) in order to accurately evaluate such a source rock. Among the hydrogen-rich components of the Jurassic coal measure source rocks in Xinjiang, vitrinite (which contains a certain amount of ultramicroscopic lipids) is absolutely dominant. The dark mudstone is relatively rich in lipid components and its oil generation potential can not be tolerated Neglect.
