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。根据湖水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。

Abstract: Five sequences were classfied in Mesozoic-Cenozoic in Junggar basin based on first-order lake level fluctuation.The favourable reservoirs include lowstand system tract, transgression system tract and slope break margin system tract, highstand system tract is both possible source bed and regional caprock.Lithological trap may be developed during second-order lake level fluctuation.This paper primarily discussed favourable reservoir facies beltvS in northwest margin in Junggar basin based on study of the lake level fluctuation and sequence stratigraphy.
