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.
