泥页岩层系中成分复杂，岩相划分方案不统一。通过岩心观察、显微镜下鉴定、全岩分析及有机地化数据分析，采用岩心宏观构造、有机质含量和岩石类型相结合的方法，以“四组分三端元”分类为原则，建立一种泥页岩层系岩相综合划分方案。结果表明：该分类方案引入有机质组分的含量，体现了泥页岩层系的构造特征、混积特征及其实用性，在苏北盆地阜二段泥页岩层系岩相划分研究中得以有效应用，可以为后续泥页岩储集空间研究、测井岩相识别和储层可改造性评价奠定基础。

The composition of shale formation is complicated, and the lithofacies classification schemes are not unified. Using core observation, microscopic identification, whole rock analysis and organic geochemical data analysis, a comprehensive shale set lithofacies classification scheme, which is based on the principle of“four-component and three-terminal element”, was established by adopting a method of combining macro structures of cores, organic content with rock types. The classifica-tion scheme introduces the organic matter content, and reflects the structural characteristics, mixed sedimentary characteris-tics of shale formations as well as its practicability. This classification scheme has been effectively applied to the study of lithofacies classification of shale set in the second Member of Funing Formation, Subei Basin, and may form a solid basis for the future shale reservoir space research, logging lithofacies identification and reservoir reconstruction evaluation.
