摘　　要：延阿参1井是部署在阿拉达布斯凹陷的一口重点钻探井,根据钻井、岩心、测井、薄片等资料,结合区域沉积演化,对延阿参1井单井沉积特征进行综合分析。研究表明,延阿参1井可划分出三角洲、水下扇、湖泊等3个大相,并细分出3个亚相11个微相。结合古环境和测井相分析,明确了阿拉达布斯凹陷沉积演化历史。YAC-1 Well is a key drilling well deployed in the Alardabus Depression.Based on drilling,core,logging,thin section,and other data,combined with regional sedimentary evolution,a comprehensive analysis of the sedimentary characteristics of the YAC-1 Well was conducted.The study reveals that the YAC-1 Well can be divided into three major facies:delta,submarine fan,and lake,with further subdivision into three subfacies and eleven microfacies.By integrating paleoenvironmental analysis and log facies analysis,the sedimentary evolution history of the Alardabus Depression is delineated.
