| 摘 要： | 通过对阿克库勒地区岩心、钻井及地震资料的分析，对三叠系进行体系域级别的沉积特征分析。识别出辫状河三角洲、湖泊和湖底扇3种沉积相，7种亚相，水上分流河道、水下主分支河道、侧缘分支河道、河口坝、补给水道、辫状沟道，远端席状砂7种砂体类型。确定了不同时期砂体分布特征，在此基础上建立了浅水型辫状河三角洲、坡折型辫状河三角洲-湖底扇、正常辫状河三角洲3种砂体分布模式。认为古地貌对区内砂体分布起重要控制作用。

| Abstract: | Based on the analysis of core,logging,and seismic data,the sedimentation characteristics are studied based on the systems tracts stratigraphic framework of Triassic system in Akekule Area.Three sedimentary facies including braided river delta,lake,sublacustrine fan,and seven subfacies are recognized.There are seven kinds of sand bodies;they are distributary channel sands,chief subaqueous distributary channel sands,subordinate subaqueous distributary channel sands,mouth bar sands,feeder channel sands,braided... |
