摘　　要：塔里木盆地卡塔克隆起"恰尔巴克组存在与否"一直存在争议,较多学者以岩石地层特征及牙形石带为依据,认为卡塔克隆起缺失恰尔巴克组。通过构造-沉积背景,结合大量岩心、岩石薄片观察、岩电特征对比、牙形石综合分析,认为卡塔克隆起存在恰尔巴克组,为深水台地相沉积,可划分为微晶灰岩、灰质泥岩、泥质灰岩、瘤状灰岩、泥岩5种微相,其中暗色泥岩在隆起区大面积分布,是良好的生油层和盖层。The question,weather the Qrebake formation exist in the Khattak uplift of Tarim basin, has always been disputed.Most scholars taking the lithostratigraphic features and the conodont belt as evidence considered the Qrebake formation has been missed,however,after the comprehensive analysis of the geology background,slices,core,the lithological electrical characteristics and conodont,the result shows the the existence of the Qrebake formation,in the Khattak uplift. And it is a deepwater platform facies.It can be divided into 5 kinds of microfacies which are matrix limestone,calcareous clay,argillaceous limestone,warty limestone and mudstone.The dark mudstone is good source rock and cap rock.
