摘　　要：从沉积相入手,通过岩心资料、测井记录的分析及层序地层的对比,发现阿克库勒地区三叠系可划分7个标准的三级层序,反映海平面7次升降旋回.在此基础上对三叠系砂体的类型及储集物性进行分析,对该区的沉积演化和层序地层格架进行归纳总结,指出该类砂体具备良好的成藏条件.The Triassic in Akekule area is divided into 7 third-order sequences based on the analyses of core data and logging record and the correlation of stratigraphic sequences.And these sequences reflect 7 fluctuation cycles of sea level.At the same time,the depositional evolution and the sequence stratigraphy framework of the area are analyzed and summarized.Based on these,the types and the physical property of the reservoir sandbody are analyzed,and it is held that this type of reservoir sand body has good reservoir forming conditions.

关 键 词：阿克库勒地区 三叠纪 层序地层 沉积相
