The paper presents the methods and steps of building 3-D migration velocity field with "Slice Method"on INTERBASE system of CGG.
本文介绍了在CGG的INTERBASE系统上用“切片法”建立三维偏移速度场的方法和步骤。
Median filtering can highlight wave band better than 2-d velocity filtering does. It also causes a better VSP wave field separation.
中值滤波较通常的二维视速度滤波更能有效地突出波组特征，分离VSP波场的效果也较二维滤波优越。
