摘要
根据一级的湖水位升降变化，准噶尔盆地中新生界可以划分为５个层序。有利的储集层位包括低水位体系域、水进体系域和坡折边缘体系域，高水位体系域既是可能的（或现实的）生油层位，也是区域性盖层。二级湖水位的升降变化可以形成有利的岩性圈闭。根据湖永位的升降变化和层序地层学研究，对盆地西北缘中新生界的储集相带作了初步预测。
Five sequences were classfied in Mesozoic- Cenozoic in Junggar basinbased on first-order lake level fluctuation. The favourable reservoirs uiclude lowstand sys-tem tract, transgression systern tract and slope break margin system tract, highstand sys-tem tract is both possible source bed and regional caprock. Lithological trap may be deve-loped during second-order lake level fluctuation. This paper primarily discussed favourablereservoir facies belts in northwest margin in Junggar basin based on study of the lake levelfluctuation and sequence stratigraphy.
