| 摘 要： | 依据层序地层学的基本理论和研究方法,综合运用露头、钻井、测井以及地震资料,对准噶尔盆地西北缘克百地区八二区三叠系克下组进行了精细的层序地层研究,建立了研究区的层序地层格架以及相应的层序地层发育模式。将研究区克下组分为一个三级层序和湖侵、湖退两个体系域。层序和体系域厚度总体上比较稳定,局部存在变化。层序中主要发育辫状河、辫状河三角洲和湖泊3种沉积相以及相应的亚相和微相。本区层序地层模式属于无法确定初次湖泛面的坳陷盆地层序地层模式。

| Abstract: | Based on the basic principles and research methods of sequence stratigraphy, a precious sequence stratigraphic analysis of the Triassic Lower Karamay Formation in Ba'er Zone of Northwestern Junggar Basin is made, using outcrops, drilling, logging, and seismic data thoroughly. The sequence stratigraphic framework of the studied area and its corresponding development model are established. The Lower Karamay Formation can be divided into one third-order sequence and two system tracts, namely, a transgressive s... |
