| 摘 要： | 运用高分辨率层序地层学的短期基准面旋回原理,详细分析了鄂尔多斯盆地西峰油田长8油组辫状河三角洲前缘的叠加水下分流河道、复合式河口坝、叠加河口坝、滑塌体及浊积扇砂体短期基准面旋回的叠加样式及储层成因.研究表明这五类砂体明显受到基准面升降、可容纳空间和沉积物补给量比值的控制.在此基础上探讨了不同砂体组合在长8层序地层格架中的展布规律.

| Abstract: | By using the short-term base-level cycle theory of high resolution sequence stratigraphy,this paper minutely analyses the overlay mode and reservoir genesis of the superposition underwater distributary channel,compound river mouth bar,superposition river mouth bar,slip block and turbidite fan sand boby in the braided stream delta front of the Triassic Chang 6-8 oil formations in the Xifeng oil field.The analysis shows that these sand bodies are evidently controlled by the short-term base-level up and down changes and the relation of accompanied accommodation and sediment alimentations.At the same time,This paper discusses the distribution of the different sand bodies combination in the Triassic Chang 8 oil formation in chrono-stratigraphic frameworke. |
