塔里木盆地北部陆相层序地层特征
|
摘要
塔里木盆地北部中、新生代陆相沉积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而完整性差；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复杂化。根据这些特点建立了层序地层格架，共划分出４５个地震及测井层序。详细描述了层序的展布及结构特征，分析表明，体系域控制了储、盖层的分布与发育。
The sequence development of Meso-Cenozoic terrestrial sedimentary strata in the northern part of Tarim basin has the following characteristics: sequence development was controlled by tectonic.action, showing obviously cyclical features, poorer completeness of sequence development due to the tectonic movement, obvious difference between the sequence features from basin margin to inner basin and the complicated textures within the strata sequences due to transgressive events. The sequence stratigraphic framework had been established, and total 45 seismic and logging strata sequences had been divided according to their features. The sequence distribution and its textural characteristics were described in detail, and the development of system tract and association of reservoir-cap rocks were also analyzed in the paper.
