摘　　要：新疆油田九6区齐古组发育一套近源碎屑沉积。目前,该区的沉积相类型仍存争论。通过对岩心、录井、测井及试油等资料数据进行研究,齐古组发育一套辫状河三角洲沉积,而非新疆油田勘探开发研究院所认为的辫状河沉积。储层分类表明:中粗砂岩、含砾粗砂岩为辫状河道沉积和水下分支河道沉积,发育I类储层;细砂岩为河口砂坝沉积,发育II类储层。为该区后续的评价、开发提供新的方法与思路。Qigu formation developed a set of near-source detrital deposit.At present,the type of precipitation facies in this area is still controversial.In virtues of investigation of drill core,well logging,testing of oil and other data,Qigu formation developed a set of braided river deltaic deposit instead of the braided river deposit that Xinjiang oil field exploration and development research institute considered.The classification of reservoir indicates that medium-coarse sandstones,pebbled coarse sandstones are braided in channel deposit and underwater branch channel deposit.And it developedⅠreservoir.Fine sandstones are river mouth bar deposit,it developedⅡreservoir.The study will provide new ideas and methods for the evaluation and follow-up development of this area.
