鄂尔多斯盆地富昌区延长组长6储层为典型的碎屑岩储层。对长6碎屑岩储层的岩石学特征、物性特征、成岩作用及分布特征进行研究,结果表明:延长组长6地层主要发育长石砂岩,岩石物性较差,为中孔低渗储层;长6储层主要经历了机械压实作用、胶结作用、溶解作用等成岩作用;长6地区储层分布主要受岩性、构造因素影响。
Chang 6 reservoir of Yanchang Formation in Fuchang District, Ordos Basin is a typical clastic reservoir. The petrologic characteristics, petrophysical characteristics, diagenesis and distribution characteristics of Chang 6 clastic reservoir are studied. The results show that the main lithofacies sandstone in Chang 6 of Yanchang Formation is poor in petrophysical properties, The Chang 6 reservoirs mainly experienced diagenesis such as mechanical compaction, cementation and dissolution. The reservoir distribution in Chang 6 area is mainly affected by lithology and structural factors.
