摘要
塔里木盆地北部中新生代陆相沉积盆地层序的发育具有以下特点：构造活动控制了沉积层序的发育，层序具明显的旋回性；层序发育受构造运动影响完整性差；盆地边缘与腹地层序特征差异明显；海侵（泛）事件影响使层序内部结构更加复杂化。根据其特征建立了层序地层格架，共划分出45个地压及测井层序．详细描述了层序的展布及结构特征，分析了体系域发育与储盖组合关系．
The sequence development of Mesozoic and Cenozoic cOntinental sedimentary basins in North Tarim Basin has characteristics as follows. Tectonic action controls the development of sedimentary sequences and sequences have obvious cyclicity,the development of sequences has bad completicity because of the effect of tectonic action and the differences of sequence characteristics between the border and the hinterland of the basin are distinct,and the effect of marine transgressive events makes the internal structure of sequences more complex. Based on the characteristics, the framework of sequence stratigraphy is established, 45 seismic and logging sequences are recognized in all, the spread and tectonic characteristics of sequences are described in detail, and the relationship of system domain development to resevoir and mantle combination is analysed.
