摘　　要：本文对伊宁凹陷的多次波叠加特性曲线、剩余时差曲线进行了研究。并利用现代计算机技术及地震反射波原理，根据地质构造模型，用射线追踪算法进行了多次波正演模拟计算。根据模拟处理结果对94S测线进行了压制多次波处理试验，得到了比较满意的结果。该研究成果为压制多次波的野外采集和室内处理提供了技术支持和借鉴经验。This thesis discussed the characteristics, stacking feature, residual moveout analysis of multiples and finishing the researching of multiple stacking feature curve and residual moveout curve. By means of advanced computer technology, principle of seismic reflection and geological model, conducted multiple forward simulation through raytrace algorithm. According to medeling result test of multiple attenuation was done for seismic line 94S and the result was satisfactory.
