| 摘 要： | 针对鄂尔多斯东部延长气区下二叠统山西组山2段低渗透气藏的特点,结合薄片观察、扫描电镜、包裹体测温、压汞等资料分析,认为该区山2段储层是1套远离岸线背景上的浅水三角洲前缘相的岩屑砂岩,受压实、胶结等成岩作用的影响,各区表现出不同的微观特征。在此分析基础上预测了延长气区山2段的勘探远景,为鄂尔多斯东部延长气田下一步勘探和开发提供了一定依据。

| Abstract: | This paper addresses the characteristics of the low permeability reservoir in the Shan 2 member of lower Permian Shanxi formation in the Yanchang gas field in eastern Ordos. Data analysis of slice observation,SEM,inclusion temperature and mercury injection demonstrates that the Shan 2 reservoir comprises lithic sandstone of shallow delta front facies far away from shoreline,with different microscopic features in different areas as affected by the diagenesis actions such as compaction and cementation. The ex... |
