塔里木盆地北部三叠系辫状三角洲砂体是本区主要的油气藏宿主储层之一，按其沉积特征可划分为前缘亚相、平原亚相．根据野外典型剖面的类比及钻井岩芯的详细分析，阿克库勒—达里亚地区的辨状三角洲砂体可划分出6组界面和9个构型单元。按其特征和规模其非均质性可分为4类级别，它们不同程度地对油气的富集起着控制作用，造成了储层沉积体在纵、横向上含油气性能的差异。
The Triassic braided delta sand body in the northern part of Tarim Basin is one of the main reservoir reservoirs in this area. According to the sedimentary characteristics, they can be divided into the frontier subfacies and the plain subfacies. Based on the typical analogy of the field and the detailed analysis of the drilling core, the deltaic sand body in the Akkule-Dalia region can be divided into six groups of interfaces and nine structural units. According to their characteristics and scale, their heterogeneity can be divided into four levels, which can control the enrichment of oil and gas in varying degrees, resulting in differences in reservoir performance between oil and gas in vertical and horizontal directions.
