| 摘 要： | 按基准面旋回原理，将鄂尔多斯盆地上古生界本溪组（C2b)、太原组（P1t）、山西组(P1s)和下石盒子组（P1xs)划分为3个超长期、8个长期、19个中期和62个短期旋回层序：较为详细地介绍了各级别层序的结构类型、叠加样式和沉积演化序列；建立以长期旋回层序为年代地层框架，中期旋回层序为等时地层对比单元的层序的地层格架；并讨论高分辨率层序地层与天然气藏的关系。

| Abstract: | Base on the theory of base level cycle, three super long term, eight long term, nineteen middle term and sixty two short term cycle sequences can be distinguished from Benxi Formation(C 2b), Taiyuan Formation(P 1t), Shanxi Formation(P 1s) and Xiashihezi Formation(P 1xs) of the Upper Paleozoic in Ordos Basin. In this paper, all graded sequences structure types, stacking patterns and sedimentary cycles are described in detail and chrono stratigraphic framework are built established on the basis of long term cycle sequences and middle term cycle sequence. The relationship between high resolution sequence stratigraphy and gas reservoir is discussed. |
