| 摘 要： | 通过野外观察、薄片鉴定、扫描电镜、阴极发光和物性等资料分析,对南祁连盆地下日哈坳陷二叠系碎屑岩储层的岩石学特征、成岩作用过程进行研究。研究结果表明：该区碎屑岩主要由石英砂岩、长石石英砂岩和长石砂岩组成,主要成岩作用类型有压实作用、胶结作用、交代作用和溶蚀作用,成岩演化阶段已达到中成岩阶段A期及中成岩阶段B期。

| Abstract: | Based on researches by means of the field observation,ordinary thin sections,scanning electron microscope and reservoir property analysis,the authors studied the petrologic and diagenetic characteristics of the Permian clastic rock reservoirs of Xiariha depression in South Qilian basin,and the result shows that clastic rock in this area are mainly composed of quartz sandstone,feldspar quartz sandstone and the feldspar sandstone and have mainly experienced such actions as compaction,cementation,metasomatism and corrosion,with the evolution reaching the middle diagenetic stage A and the middle diagenetic stage B. |
