摘　　要：基于Vail为代表的层序地层学理论 ,引入了高分辨率层序地层学中的基准面和可容空间的概念 ,综合运用地质、测井和地震资料 ,对准噶尔盆地白家海五彩湾地区的层序地层进行了研究。将研究区的苍房沟群和小泉沟群划分为A ,B ,C ,D 4个层序 ,分别对应梧桐沟组、韭菜园子组、烧房沟组和小泉沟群。同时依据基准面升降旋回的概念 ,将每一个层序都划分为基准面的上升和下降旋回。综合考虑可容空间、沉积物供给以及两者的匹配关系 ,建立了 5种层序地层模式。研究结果表明 。On the basis of the basic principles of sequence stratigraphy, the concepts of base level and accommodation were introduced to research the sequence stratigraphy in Baijiahai and Wucaiwan areas of the Junggar Basin, by the use of the data of geology, logging and seismic. The Cangfanggou Group and Xiaoquangou Group were divided into four sequences that correspond respectively to Wutonggou formation, Jiucaiyuanzi formation, Shaofanggou formation, Xiaoquangou group. Each sequence was divided into the descending cycle and rising cycle of the base level. In consideration of accommodation, supply of sediments and mutual relationship of them, five kinds of sequence stratigraphy models were established. The analyses on the changes of the base level and the supply of sediments show that the development of the four sequences in these areas is controlled by the change of the base level and supply of sediments.
