摘　　要：根据层序地层的划分与对比,塔里木盆地沙雅隆起塔河地区石炭系可划分为6个标准三级层序,反映了海平面的6次升降旋回。在归纳总结塔河地区石炭纪沉积演化和石炭系层序地层格架的基础上,根据沉积相分析并结合海平面变化对地层沉积及演化的影响,认为塔河地区下石炭统巴楚组砂砾段与塔中、满西地区的生屑灰岩段为同期沉积,岩性的差异是同期异相的结果。The sequence stratigraphic correlation reveals 6 level-3 sequences in Tahe area, which reflects 6 times of sea-level fluctuation cycle. Combined with the analysis of depositional facies, the sandy-conglomerate member in Tahe area was deposited at the same time with the bioclastic-limestone member in Tazhong and Manxi area. The lithological difference is mainly caused by different depositional facies in the same time.
