摘要：

以湖盆中心典型露头剖面及成熟井区为研究对象，依据室内分析化验手段，对鄂尔多斯盆地延长组深水砂岩储层岩石学特征进行了综合分析。研究发现延长期湖盆中心不同部位深水砂岩组分、矿物成分、填隙物类型及含量都存在明显的区别，甚至同一类型岩石中矿物含量也存在差异。这种岩石学特征上的差异主要受盆地周缘不同沉积物源体系的控制，反映了不同物源条件下的母岩性质。岩石学特征研究能对深水砂岩类型及储层条件进行评价，为盆地油气勘探开发提供科学依据。

Abstract:

Based on the analysis of typical outcrops and well areas,combined with indoor test data,the reservoir petrology of deep water sandstone of Chang 6 Formation in Ordos Basin has been investigated.The result shows that it varies greatly in different places,involving sandstone component,mineral composition,interstitial material component and their contents.Moreover,the mineral contents have a wide difference in the same type of sandstone.These differences are controlled by sedimentary source systems in the margin of Ordos Basin.It reflects the different nature of source rocks.The study of reservoir petrology can estimate the type of deep water sandstone and reservoir conditions,also provide the basis for exploration and development of oil and gas in the basin.

Key words: Reservoir petrology, Sedimentary systems, Deep water sandstone, Ordos Basin
