摘　　要：鄯科1井是吐哈盆地台北凹陷首次钻穿三叠系的一口科学探索井,并在三叠系发现了轻质油流.依据鄯科1井的钻后评价成果,从油源对比与烃源岩演化、储层发育特征与次生孔隙形成机理、盖层特征、圈闭演化历史、油气运移方向及通道等多方面分析了鄯深构造三叠系油藏的成藏条件,并指出鄯善弧形带和葡北构造带是台北凹陷深层下一步油气勘探的较有利的区带.As a scientific research well, Shanke?1 has made the first penetration through light oil in Triassic and found light oil in Triassic in Taibei Depression, Tuha Basin. According to the post_drilling evaluation in Shanke?1, Triassic oil_accumulation conditions for Shanshen structure are analyzed from several aspects, such as oil_source correlation, source maturation correlation, reservoir development, secondary porosity, seal characteristics, trap evolution history, and hydrocarbon migration direction and pathway, and it is pointed that the Shanshan arcuate zone and Pubei structural zone are more favorable plays for next exploration in deeper Taibei Depression.
