摘　　要：石炭系是准噶尔盆地车排子凸起发育的一套重要勘探层系。利用录测井、岩石薄片、扫描电镜及地震等资料,分析石炭系储层发育特征与主控因素,建立研究区石炭系储层发育模式。结果表明:车排子凸起东翼与西翼石炭系储层类型不同,凸起东翼以火山岩储层为主,岩性为火山角砾岩、凝灰岩、安山岩、玄武岩,沉积岩类储层不发育;凸起西翼火山岩及火山沉积岩储层发育,岩性以凝灰岩与凝灰质砂岩为主。岩性岩相、风化淋滤与构造运动等因素控制储层的发育,车排子凸起发育两类储层模式,即凸起东翼发育裂缝-风化壳主导型储层模式,凸起西翼发育岩性-裂缝主导型储层模式。该结果可指导车排子凸起石炭系储层的勘探部署。The Carboniferous is the major exploratory target in Chepaizi Uplift of Junggar Basin.To identify the predominant factors and development mode of Carboniferous reservoirs,we analyzed the Carboniferous reservoir characteristics and predominant factors based on a large number data of well logging,well drilling,rock slices,scanning electron microscope,seismic data,etc.Finally we established two types of development mode of reservoirs based on the research of the predominant factors.Research results show that the types of Carboniferous reservoirs in the east flank and west flank of Chepaizi Uplift are different,which developed volcanic reservoirs in the east flank while sedimentary rock does not develop reservoir,but the west flank developed tuff and tuffaceous sandstone reservoirs.The predominant factors of reservoirs included lithology and lithology and lithofacies,weathering,tectonism.There were two types of development pattern of Carboniferous reservoirs in Chepaizi Uplift,namely the"fractureweathering crust"dominated reservoir in the east flank and"lithology-fracture"dominated reservoir in the west flank.Research results effectively guide the exploration and deployment of Carboniferous reservoirs in Chepaizi Uplift.
