摘　　要：从区域地质背景出发,通过层理构造、岩石颜色、粒度分析、颗粒结构、测井相以及单井相的综合分析表明,鄂尔多斯盆地盘古梁地区长61层段主要为河湖交汇区三角洲前缘亚相沉积体系,物源方向为北东向。研究区内主要发育水下分流河道、河口砂坝、水下天然堤、支流间湾微相。水下分流河道及河口砂坝有利储集相带是油藏形成的地质基础。Based on the area geologic background,integral analysis on the bedding structure,colour of rocks,particle size and structure,log facies as well as single well facies indicates that Chang 61 section in Pan GuLiang district Ordos basin is of deltar front facies depositional systems.The source materials to this area is from Northeast.The study area mainly developed subaqueous distributary channel,channel mouth bar,subse natural barrier and distributary channel.subaqueous distributary channel and channel mouth bar is the basis of reservoir geological formation.
