| 摘 要： | 主要应用Cross的高分辨率层序地层学理论及其技术方法，对酒西坳陷青西凹陷下沟组进行了层序地层划分，从中划分为2个长期和5个中期数十个短期基准面旋回层序，分析了不同级次的基准面旋回结构、叠加样式、分布模式，及其与储集砂体的发育关系，探讨了地层格架中生、储、盖组合和有利储集相带和铁白云石—钠长石质喷流岩的平面分布规律。

| Abstract: | Based on the theory and technology of Cross′s high resolution sequence stratigraphy, and two long term, five middle term and above ten short term cyclic sequences from Xiagou Formation of Lower Cretaceous in Qingxi Sag, Jiuquan Basin were classified. The structure types, stacking patterns, distributing mode and development relation to reservoir sand body of short term, middle term, long term cyclic sequences are analyzed. The source reservoir seal associations and the plane distribution rule of ferrodolomite albite exhalative rock in the chrono stratigraghic framework are discussed in detail. |
