摘　　要：中侏罗统头屯河组为准噶尔盆地东部阜东斜坡带最重要的勘探层系,利用多种分析和测试手段,对准噶尔盆地阜东斜坡带头屯河组二段储集层岩石学、储集空间以及物性特征进行研究,并详细分析储集层控制因素。研究表明,研究区头屯河组二段岩性主要以细粒岩屑砂岩为主,储集空间主要以原生粒间孔为主,属于中孔中低渗储集层。物源和异常高压带影响储集层的物性,沉积相及古地貌控制储集层分布规律,黏土矿物类型及含量影响储集性能。The Toutunhe formation of Middle Jurassic is the main sequence for oil exploration in Fudong （eastern Fukang） slope zone in eastern Junggar basin.By means of many analyses and testing methods,this paper studies the characteristics of lithology,reservoir space and physical property of the second member of Toutunhe formation in the Fudong slope zone,including the reservoir controlling factor analysis in detail.The results show that the lithology in this member is dominated by fine arenstritic sandstone,the reservoir space is dominant by primary intergranular pores,belonging to medium-porosity and medium-low-permeability reservoir.The reservoir physical property is controlled by the provenance and abnormal pressure zone,the reservoir distribution is controlled by the sedimentary facies and paleo-geomorphology,and the reservoir quality is controlled by the clay minerals types and contents in this area.
