摘　　要：沙沟地区位于鄂尔多斯盆地伊陕斜坡中部,延9油层是其主力油层。根据大量岩心及测井曲线分析,研究区为三角洲平原沉积相,可进一步识别出分流河道、分流间湾和决口扇微相,其中分流河道微相是重要的油气富集区,是今后勘探开发的重点。Shagou is located in central area of Shanbei slope in Ordos basin.Major reservoir is Jurassic Yan'an 9 formation.According to observation of a large number of cores and well log analysis,Shagou area Yan 9 formation is mainly considered to delta plain facies,and further recognized the distributary channel,interdistributary bay and splay facies.The channel deposit is a good reservoir,and also is the direction of developing this area.
