摘　　要：塔北中、新生代油气藏的分布主要与古隆起、斜坡区和与之伴生的断裂和逆掩褶皱带有关。油气藏纵向上呈双层结构，形成３个聚集成藏模式：天山山前逆掩褶皱带模式、坳陷区模式和隆起区及斜坡带模式。勘探和地质条件分析表明，库车坳陷是本区唯一能发现大油气田的地区，雅克拉断凸－沙西北部、沙西凸起、阿克库勒凸起及隆起斜坡地区是寻找新的中小型油气田（藏）的有利地区。The distribution of Meso-Cenozoic oil (gas) pools in Northern Tarim is primarily related to paleo-uplifts, paleo-slopes and the associated faults and overthrust-fold zones. Vertically the reservoirs are composed of Meso-Cenozoic double-layer texture; horizentally they could be divided into Tianshan piedmont overthrust-fold zone, depressed zone and uplift (including slope) zone. Geological data analysis indicates that Kuqa Depression is the only place to discover large oil fields in the study area; Yakela faulted uplift-northwest Shaya uplift, west Shaya uplift, Akqule uplift and the slope areas are favourable for seeking mid to small size of oil and gas fields.
