摘要: 吐哈盆地台北凹陷内二叠、三叠系两套烃源岩厚度大且分布稳定、具备良好的生烃条件, 发育三套生储盖组合, 以上二叠统为生油层,中、上三叠统为储油层的生储盖组合最为有利, 而南部辫状河三角洲砂体是主要的储集体类型;下侏罗统存在两套局部储盖组合,其圈闭分布与二叠、三叠系的圈闭分布基本一致。综合评价认为:鄯善孤形带、红连区带、葡北带和北部山前带是台北凹陷开展深层油气勘探的有利区带。

Abstract: Permian and Triassic source rocks have large thickness, stable distribution and better hydrocarbon-generation condition in Taibei sag of Turpan-Hami basin.Three sets of source-reservoir-cap assemblages are developed in Taibei sag, in which the combination of Upper Permian as source rock and Mid-Upper Triassic as reservoi r is the most favourable one, braided river delta sandbody in the south is dominant in reservoir type;two sets of local reservoircap assemblages occur in the Lower Jurassic, the distribution of thei r traps coincides with Permian and Triassic traps.Comprehensive evaluation considered that Shanshan arc-like belt, Honglian area, Pubei and northern piedmont belts are favourable one for deep hydrocarbon exploration in Taibei sag.
