摘　　要：应用层序地层学和沉积学的原理与方法,综合岩心、钻井以及测井和地震资料,对塔西南地区白垩系进行了深入的研究,划分出2个二级层序和3个三级层序,建立了塔西南地区白垩系层序地层格架。在研究区识别出冲积扇、扇三角洲、有障壁滨岸和开阔台地4种沉积相。以层序格架内沉积相的展布特征,揭示了层序格架内沉积相的演化规律。Based on the principle and method of sequence stratigraphy and sedimentology, combined with core, drilling, logging and seismic data, the Cretaceous in southwestern Tarim area were studied and divided into 2 second order sequences and 3 second order sequences. The Cretaceous sequence stratigraphic framework in the southwest Tarim basin was established. In the study area, 4 sedimentary facies were identified： alluvial fan, fan delta, barrier coast and open platform. Based on the distribution characteristics of sedimentary facies in sequence framework, the evolution law of sedimentary facies in sequence framework was revealed.
