migration velocity

基本解釋

Migration velocity analysis is one of the key steps in pre stack depth migration whose accuracy directly affects the quality of pre stack depth migration.
偏移速度分析是疊前深度偏移的關(guān)鍵步驟之一，它的準(zhǔn)確與否直接影響疊前深度偏移的質(zhì)量。
Migration velocity is the key factor which influences the migration result.
偏移速度是影響偏移效果的關(guān)鍵因素。
The paper presented split-step Fourier presta- ck depth migration method using velocity structure to partition the velocity field.
本文提出了一種按速度構(gòu)造對速度場進(jìn)行分區(qū)的裂步傅里葉疊前深度偏移方法。
