摘要： 吐哈盆地是一个陆相含 油气盆地,侏罗系是主要的勘探目的层。运用层序地层学的理论和方法，通过对露头剖面、钻井和地震等资料的综合研究,可将侏罗系划分为七个层序(SQi-SQ>)。层序SQ.相当于八道湾组和三工河组,SQ2相当于西山窑组一二三段,SQ3相当于西山窑组四段和三间房组-段,SQ4相当于三间房组二三段,SQ3、SQ6和SQ,分别相当于七克台组、齐古组和喀拉扎组。煤系烃源岩主要分布于层序SQ1和SQ2的基准面上升半旋回的上部,储集层主要发育在层序SQ1SQ2、SQ3、SQ4和SQs上升半旋回，层序SQ3、SQ4SQs下降半旋回和SQ6SQz层序是区域盖层发育的主要层位。

Abstract: Turpan-Hami basin is a continental petroliferous basin in which Jurassic is its major prospected stratum. By using theory and methodof high-resolution sequence stratigraphy, comprehensive studies of the outcrop section, drilling and seismic data are made, and the Jurassic isdivided into seven sequences (SQ,-SQ-). SQ, corresponds to Badaowan formation and Sangonghe formation; SQ, to the first, second and thirdmembers of X ishanyao formation;SQ3 to the fourth member of Xishanyao and the first member of Sanjianfang formation; SQ4 to the second andthird members of Sanjianfang; SQs, SQ6 and SQ- to Qiketai, Qigu and Kalazha formations, respectively. The coal measures source rocks are mostdistributed in the upper part of SQ1 and SQ-base-level rising hemicyclothem; the reservoir mainly in SQ,-SQ5 rising hemicyclothems. The SQ3,SQ4 and SQ5 base-level falling lenicylothemas well as SQ6 and SQ6 and SQ7 are the majorizons sf regional cap rocks in this basin.
