| 摘 要： | 滩坝砂岩是我国陆相盆地重要储集类型之一，由于其厚度较薄，储层分布预测的难度较大。对车镇凹陷沙二段滩坝砂体进行了解剖性研究，总结了“滩”和“坝”的识别标志，指出二者在分布特征、沉积厚度、粒度与几何形态等方面均有明显差异。运用以基准面为参照面的高分辨率层序地层学方法划分了滩坝层系的等时地层单元，分析了“滩”“坝”砂的分布规律。探讨了湖盆结构、古地貌、物源供给、水动力等条件对滩坝砂体形成与分布的控制作用。在此基础上，建立了沙二段滩坝砂体成因模式，为滩坝砂体储层油气勘探提供了地质依据。

| Abstract: | Sand bank sandstones are one of the important reservoirs in nonmarine basins of China.Bank genetic reservoir prediction is not easy due to its thin bed characters.This paper summarizes the identification marks of sand bank and barrier in lake.Isochronous stratigraphic units are divided based on high-resolution sequence stratigraphy principle,sand bank and barrier distribution and its controls are analyzed in time stratigraphic units,and also sedimentary models of bank and barrier are established.This study provides the geologic foundation for oil and gas exploration in sand bank reservoirs. |

| Keywords: | bank and bar high resolution sequence time-space distribution genetic model control factors |
