| 中文摘要:在高分辨层序地层的理论中，基准面的升降和旋回期的长短变化影响着层序内部沉积体系的发育。但要注意的是，盆地的原始古地貌作为层序发育的背景，很大程序上影响着基准面变化导致的可容纳空间大小的变化，对沉积物的体积分配和相分异有特定的控制作用。同时古地貌形态会在层序格架中发生演化，变得逐渐不明显或最终消失。文中论述了古地理特征识别及其重要性；以鄂尔多期盆地为例研究了古地貌对层序中发育规律的影响，重点论述了发育较广泛的古凸起带呼下切沟谷带基准面旋回变化而不同类型储集体发育所产生的影响。 |

| Abstract:According to high resolution sequence stratigraphy, changes in base level and cycles can affect the development of depositional system. The distribution and style of depositional system are controlled by the changes of base level. It should be pointed out that the palaeotopography exerts a great effect on the accommodation space affected by base level changes, and plays a special controlling part in sediment volume partitioning and facies differentiation. In this paper, the significance of palaeotopography determination is discussed. It can be concluded that the research on palaeotopography can play a leading role in reservoir prediction. |
