根据沉积特征、岩石矿物特征、生物特征及地球化学特征的综合分析 ,将塔里木盆地白垩—第三系划分为 3个沉积相组、12个沉积相、2 0个沉积亚相和若干个沉积微相 ,并首次在塔北发现海相沉积。塔里木盆地白垩—第三纪储集体包括碎屑岩和碳酸盐岩两种。东北坳陷区储层主要为碎屑岩 ,特别是下白垩统卡普沙良群亚格列木组是沙雅隆起上的重要储层 ,上白垩统巴什基奇克组是库车前陆盆地的重要储层。西南坳陷区储层包括碎屑岩储层和碳酸盐岩储层两种岩性 ,如下白垩统上部乌鲁克恰特组滨岸海滩砂砾岩及上白垩统依格孜牙组生物丘灰岩等也构成较好的储集层。
Based on the comprehensive analysis of sedimentary characteristics, rock mineral characteristics, biological characteristics and geochemical characteristics, the Cretaceous-Tertiary in the Tarim Basin is divided into three sedimentary facies, 12 sedimentary facies, 20 sedimentary subfacies and several sedimentary micro-structures Phase, and for the first time in northern Thailand found marine sediments. The Cretaceous-Tertiary reservoirs in the Tarim Basin include both clastic rocks and carbonate rocks. The reservoirs in the northeastern depression are mainly clastic rocks, especially the Cretaceous Kapuzhaliang Yagelimu Formation, which is an important reservoir on the Shaya Uplift. The Upper Cretaceous Bashijiqike Formation is a member of the Kuqa foreland Important reservoir in the basin. The Southwest Depression area consists of clastic reservoir and carbonate reservoir lithology, as follows Upper Cretaceous Urukchart bank shore beach sand conglomerate and Upper Cretaceous Yigeziya group bio-mound Limestone also constitutes a better reservoir.
