摘　　要：准噶尔盆地腹部侏罗系埋藏深,地震资料在目的层分辨率较低、地震反射特征不清晰,制约了对该区的低幅构造、岩性圈闭的识别和评价.地震物理模拟提供认识复杂地震波场的直观手段.通过建立永进地区、莫西庄符合准噶尔盆地腹部侏罗系油藏实际的物理模型,进行地震物理波场模拟,研究了准噶尔盆地腹部侏罗系含油气地层的地震属性特征,为有效识别侏罗系油藏提供有力了依据.The Jurassic buries deep in central Junggar Basin. Seismic data from the targets is characterized by low resolution and unclear reflection character, which impedes the identification and assessment of low relief structures and lithological traps. Seismic physical modelling provides a intuitional means for recognition of complex wavefield. In this paper, we construct two realistic physical models based on the structures in Yongjin and MoxiZhang regions in central Junggar Basin to simulate the seismic wavefield of the Jurassic. The results provide insight for the description of Jurassic reservoir in Junggar Basin
