摘　　要：对准噶尔盆地阜东斜坡区侏罗系地层进行了研究 ,选择了可信度较高的地震反射内部结构和外部形态 ,辅助地震反射振幅、连续性等参数 ,对地震相进行了划分命名。在研究区 6个地震层序中共识别出平行席状地震相、亚平行席状地震相、前积地震相、亚平行波状乱岗状地震相、透镜状地震相、充填地震相及楔状地震相等多种地震相类型。这些地震相在平面分布上具有差异性 。Seismic facies of Jurassic system on East Fukang slope in Junggar Basin are divided and named mainly based on the reliable internal reflection texture and external shape of the seismic sequence unit. Amptitude, continuity and other seismic parameters are also used in description of seismic sequence units. In the study area,six seismic sequences are divided and more than seven seismic facies are identified, including parallel mat shaped, subparallel mat shaped, foreset, wave shaped, lenticular, filling and wedge shaped seismic facies, which show differentiation in spatial distribution and hereditability and differentiation in vertical evolution.
