摘　　要：塔里木盆地北部中、新生界油气藏形成条件较好，其中储、盖及其组合条件优越，油气条件中等，圈闭及运移条件中等—偏差，油气藏保存条件中等—偏差。在库车坳陷具有形成大油气田的条件，其余广大地区，在组合条件较好的地区可形成中—小型油气田（藏）群。本区中、新生界油气田（藏）的分布具三种模式。目前区内从震旦系至上第三系９个层系内发现的规模不等的油气藏，有８０％集中在中、新生界内（主要分布在古隆起及斜坡带），证明其有广阔的油气勘探远景。The conditons for generation of oil-gas Pool are pretty good, among which those of reservoirs,roof rocks and combination are excellent, those of oil-gas are medium, those of trap and migration are medium to poor, and those of oil-gas storage are medium to poor. Kuqa depression owns conditions to form largescale oil-gas fields, other areas with better combination conditions may form groups of medium-small,cale oil-gas fields (pools). The Meso-Cenozoic oil-gas pools of this region are distributed in three models, mainly in palaeo-uplift and slope zone, and occupies 80% of the total from Sinian ito Neogene, implying a good oilgas exploration prospect of peso-Cenozoic in this region.
