摘　　要：由于对塔里木盆地阿满过渡带东部中-下奥陶统特深层碳酸盐岩断控储层特征及主控因素认识不足,一定程度上限制了该地区的井位部署和开发方案编制。为此,利用岩心、铸体薄片、成像测井图像、测井曲线和生产动态等资料对阿满过渡带东部中-下奥陶统储层特征和主控因素进行研究。结果表明:阿满过渡带东部中-下奥陶统碳酸盐岩断控储层以亮晶砂屑灰岩为主,可见断裂空腔、角砾间孔、溶蚀孔洞、晶间孔、晶间溶孔、宏观构造缝、构造裂缝、缝合线、溶蚀裂缝9种储集空间类型,主要的储层类型有洞穴型、裂缝-孔洞型及裂缝型;储层发育主要受控于沉积作用、断裂作用和岩溶作用,即高能滩背景下的颗粒灰岩为储层发育提供物质基础,走滑断裂是储层形成的构造前提,岩溶作用对研究区储集空间具有改善作用,促进了储层的发育。As the lack of indepth understanding of the characteristics and main control factors of carbonate faultcontrolled reservoirs of the middlelower Ordovician extradeep carbonate rocks in the eastern part of the Aman transition zone in the Tarim Basin,the well location deployment and development plan preparation in this area are limited to a certain extent.Therefore,the characteristics and main control factors of the middlelower Ordovician reservoirs in the eastern part of the Aman transition zone are studied by using the data of cores,casting thin sections,imaging logging images,log and production performance.The results show that the faultcontrolled reservoirs of the middlelower Ordovician carbonate rocks in the eastern part of the Aman transition zone are dominated by sparry arenaceous limestone,and there are 9 reservoir space types,including fractured cavities,breccia pores,dissolved vugs,intercrystal pores,intercrystalline dissolved pores,macroscopic structural fractures,structural fractures,stylolites and dissolued fractures,and the main reservoir types are cave,fracturedvuggy and fracture.The development of reservoirs is mainly controlled by sedimentation,faulting and karstification,that is,grainstone under the background of highenergy shoals provides the material basis for reservoir development,strikeslip faults are the tectonic prerequisites for reservoir formation,and karstification has an improving effect on the reservoir space in the study area and promotes the development of reservoirs.
