摘要
以塔里木盆地加里东期和海西两期构造运动为背景,结合现有的岩心、露头、测井、录井和地震资料,对巴楚组可识别出早期的辫状河三角洲沉积,中期的潟湖沉积和盐湖沉积,以及晚期的咸化潟湖沉积。本文分别从横向上和纵向上对塔河地区巴楚组沉积演化进行深入分析;总结了巴楚组构造运动与沉积响应之间的关系,以期为该地区的下石炭统巴楚组的进一步勘探提供科学依据。
In the light of cores, well logs and seismic data, referenced to the tectonic interpretation of the study area, the Lower Carboniferous Bachu Formation in the Tarim River area, Xinjiang has experienced three phases of sedimentary evolution including the braided delta deposits in the early stage, lagoon and salt lake deposits in the middle stage, and salinized lagoon deposits in the later stage. The present paper deals laterally and vertically with the sedimentary evolution, and sedimentary response to the tectonic movements in the Bachu Formation, aiming at providing a scientific basis for future exploration of the Bachu Formation.
