摘　　要：中东卡塔尔地区二叠系Unayzah组属于鲁卜哈利富油气盆地的探索新领域,整体勘探程度较低,鉴于沉积相类型的确定对储集相带预测、储层评价具有重要意义,综合分析了岩心及钻录井资料,探讨了中东卡塔尔二叠系Unayzah组沉积相类型:依据颜色、岩石结构、沉积构造等一系列沉积相标志,判定Unayzah组主要发育辫状河相和三角洲相2种沉积相、4种沉积亚相以及6种沉积微相;结合地震资料分析得出了Unayzah组沉积时期的沉积相展布特征。The Unayzah Formation,a strata of Permian in Qatar of Middle East,is located in the new exploration area of RubAl Khali Basin with rich oil and gas,it was hardly explored before.As the determination of sedimentary facies plays a important role in the prediction and evaluation of reservation,the sedimentary facies type of Unayzah Formation is discussed based on the comprehensive analysis of core and logging data,it is judged that the braided river facies and delta facies contain four subfacies or six microfacies with two major sedimentary facies types in the Unayzah Formation,and the sedimentary facies distribution in this period is combined with the result of seismic data interpretation.
