摘　　要：基于岩心观察与描述、铸体薄片鉴定,采用物性测试、扫描电镜等方法,研究准噶尔盆地阜东斜坡带三叠系韭菜园子组储层特征和控制因素,进行储层分类评价及预测。结果表明:准噶尔盆地阜东斜坡带三叠系韭菜园子组储层岩石类型以长石岩屑砂岩和岩屑砂岩为主,储层物性整体表现为中孔低渗。不同构造区域储层特征有差异,沙丘凸起物性以中高孔低渗为主,储集空间大,原生、次生孔隙较为发育;北三台凸起物性以中孔中低渗为主,储集空间类型多样;沙奇凸起物性相对较差,以低孔低渗为主,储集空间少,以次生孔隙为主。韭菜园子组储层物性受岩相、成岩相控制,划分6种岩相和7种成岩相类型,总结15种岩相—成岩相综合相类型;划分4类储层,从Ⅰ类到Ⅳ类储层物性依次变差,沙丘凸起以Ⅰ类和Ⅱ类储层为主,北三台凸起以Ⅱ类和Ⅲ类储层为主,沙奇凸起以Ⅳ类储层为主。该结果为研究区油气预测和开发提供参考。Based on core observation and description,casting thin section identification,physical property test,scanning electron microscope and other analytical methods,the reservoir characteristics and controlling factors of the Triassic Jiucaiyuanzi Formation in Fudong Slope Belt in Junggar Basin were clarified,and the reservoir was classified,evaluated and predicted.The results show that the rock types of the Triassic Jiucaiyuanzi Formation are mainly as feldspar lithic sandstone and lithic sandstone.Among all kinds of debris types,volcanic rock debris is the most abundant.The reservoir physical properties of the study area are generally characterized by medium porosity and low permeability.There are differences in reservoir characteristics in different structural regions.Among them,the physical properties of the Shaqiu Uplift are mainly medium and high porosity and low permeability,with large storage space and relatively developed primary and secondary pores.The physical properties of the Beisantai Uplift are mainly medium porosity and low permeability,and the storage space types are various.The physical properties of the Shaqiu Uplift are relatively poor,which mainly characterized by low porosity and low permeability,meanwhile,the reservoir has less storage space,which dominated by secondary pores.The reservoir physical properties of the Triassic Jiucaiyuanzi Formation in the study area are controlled by the lithofacies and diagenetic facies joint.There are six types of lithofacies and seven kinds of diagenetic facies,which can be divided into sixteen combinatwordion types of sedimentary-diagenetic facies,and there are four types of reservoirs,among which the physical properties be worse fromⅠclass toⅣclass in turn.The reservoirs are predicted by logging identification,the types of reservoirs in the Shaqiu Uplift are given priority to withⅠclass andⅡclass.In the Beisantai Uplift,all types of reservoirs are developed,andⅡclass andⅢclass are accounted for most.The main reservoir type isⅣclass in the Shaqiu
