摘　　要：新疆油田九_6区齐古组发育一套近源碎屑沉积。经过实验区及全区的小层划分与对比,可以看出西北部地层厚度较大;通过砂地比、砾地比分布等值线图,可以直观地反映西北部的砂地比、砾地比值高于研究区东南及其他地区以及对重矿物鉴定分析,可以反映齐古组物源方向主要来自九_6区西北部。研究将为该区后续的沉积相特征研究及储集砂体的特征研究提供思路与依据。The Qigu Formation developed a set of near-source detrital deposit.After dividing and contrasting the stratums of the experimental area and the whole area,the thickness of the northwest layers was shown to be biggish.In virtue of the figures of sand ratio and gravel ratio,the northwest sand ratio and gravel ratio were intuitionally seen to be higher than that in the southeast and other areas of the study area.In the meanwhile,the identification and analysis of heavy mineral was also clearly shown.In addition,the orientation of mineral source in Qigu Formation was reflected to mainly from the northwest Ⅸ 6 well block.The study will provide new ideas and methods for the follow-up research of the feature of sedimentary phase and reservoir sand body.
