【摘要】 以vail层序地层学理论为指导,按照层次分析、逐级深入、聚焦含油气高分辨层序地层单元的思路,建立了准噶尔盆地白垩系的三级层序地层格架。同时,结合北三台西斜坡的三维地震数据、钻井、测井和分析化验等资料,通过建立9条层序地层地震解释剖面和联井对比剖面,刻画了北三台西斜坡白垩系的层序地层特征。在上述研究的基础上,针对白垩系下部层序单元进行高频层序地层的划分,并确定主要含油气高分辨率层序地层单元,有助于在后续构造、沉积相研究和勘探工作中抓住重点,对北三台西斜坡白垩系下一步的勘探部署有重要的指导意义。更多还原

【Abstract】 Three-level stratigraphy sequence framework for Junggar Basin Cretaceous is established in the light of stratigraphy theory of Vail stratigraphy sequence and based on the thought path of layer-by-layer analyses and gradual stepping to and focusing on layer unit containing oil with high resolution stratigraphy sequence.Meanwhile,the characteristics of stratigraphy sequence layers is described by establishing seismic interpretation profile and correlation profile among wells of 9 stratigraphy sequence layers based on the integration of the data of 3D seismic,drilling,logging,analytical test and so on.Based on the study made above,the layers with high frequency stratigraphy sequence are classified for the lower stratigraphy sequence units of Cretaceous and the layer units with high frequency stratigraphy sequence are determined,which is conducive to the key jobs of the study and exploration of structures and sedimentary facies in the future and is significant to the future exploration arrangement in Cretaceous of West Slope of Beisantai.更多还原
