摘　　要：泌阳凹陷南部陡坡带核三段发育了3种不同类型的沉积砂体:扇三角洲砂体、辫状河三角洲砂体、曲流河三角洲砂体。不同类型的砂体分布在凹陷区域的不同位置,受物源等地质条件的影响,其砂体沉积特征及储集性能和油气的分布均有明显的差异。通过对岩石组成、层理类型、内部相带的发育情况等的分析,阐述了3种类型沉积砂体的特征,并进一步对3种沉积砂岩的储集性能及其油气分布进行论述,从而为该地区的油气勘探开发提供依据。There were three different types of sedimentary sandstone of the Eh3 member in the southern steep slop zone of Biyang Sag: Fan-delta sand body,braided delta sand body and meandering river delta sand body.Different types of sand were found in the Biyang Sag of the different locations,under the impact of the geological conditions,there are significant difference in sand body sedimentary characteristics,reservoir properties and reservoir distribution.Three types of sedimentary sand body characteristics are described by rock composition,bedding types and the internal phase with the development,and it is discusses three kinds of sedimentary sandstone reservoir properties and reservoir distribution in further.
