摘　　要：根据钻井和测井资料,以不整合和沉积作用转换面为界,将沙湾组-塔西河组划分为6个长期基准面旋回.通过分析,短期基准面旋回主要有4种样式,分别由辫状河道、决口扇、辫状河三角洲分支河道和河口坝4种沉积微相组成.根据短期旋回的叠加样式及关键界面对测井曲线的标定结果,建立古近—新近系中期基准面旋回的测井解释模型,将其划分为11个中期基准面旋回.通过分析发现,基准面旋回控制油气成藏和油气分布规律.Based on drilling and well logging data, the Tertiary System was divided into six long_term base_level cycles by unconformity and sedimentary transform surfaces. There are mainly four types of short-term base-level cycles, which control the formation of braided channel, crevasse splay, coastal-shallow lagoon sheet sand, mouch bar and distributary channel sediments of braided stream delta. According to staching patterns of short-level cycles and calibration of logs restrained by key interfaces, alog interpretation model for the Tertiary System medium-term base levels. Eleven medium-term base levels were divided. After analysis, the relations between base-level cycles and oil accumulation and distribution are intimate.
