在岩心观察描述基础上，结合钻、测井数据和三维地震资料探讨了准噶尔盆地西泉（XIQ）地区下三叠统韭菜园子组高分辨率层序地层特征及储层分布。文中采用高分辨率层序划分和对比理论和方法，将研究区下三叠统韭菜园子组划分为3类基准面短期旋回、5个基准面中期旋回、2个基准面长期旋回，并运用钻井约束下的地球物理分频反演技术，对目标层序内储集砂体空间展布进行了预测，提出基准面的变化控制了研究区韭菜园子组砂体的空间展布和有利的砂体发育带，指明了下一步勘探和评价的方向。

Based on core logging and 3D-seismic data, the high-resolution sequence stratigraphy of the Jiucaiyuanzi formation of the Lower Triassic Formatin in XIQ area of Eastern Junggar Basin is studied. Three kinds of short-term base-level cycles, five intermediate-term base-level cycles, and two long-term base-level cycles can be identified with the technology of division and correlation of the high-resolution sequence stratigraphic theory. Based on the base-level cycles, reservoir sands in different sequences are predicted with the technology of the frequency-divided inversion. Base-level changes control the spatial distribution of the sandstone of the Jiucaiyuanzi formation of the lower Triassic Formatin in XIQ area. The favorable sand bodies are predicted. The targets for further exploration and evaluation are identified.
