摘　　要：通过岩心观察、铸体薄片鉴定、阴极发光、扫描电镜观察等方法,对鄂尔多斯盆地靖边气田北部奥陶系马52亚段碳酸盐的岩成岩作用进行了详细的研究,研究结果表明马52亚段储层的主要成岩作用类型为压溶及机械压实作用、胶结作用、交代作用和溶蚀作用。Through the observation of core, identification of thin slices, cathodoluminescence and scanning electron microscopy, the diagenesis of carbonate in the Ordovician 52 sub-section of the Jingbian gas field in the Ordos Basin was studied in detail. The results show that the horse 52 The main diagenetic types of sub-sector reservoirs are pressure- dissolution and mechanical compaction, cementation, metasomatism and dissolution.
