shot record migration 中文意思是什麼
shot record migration
解釋
共炮點-
The migration results of the synthetic and ocean field datasets show that this method is correct and effective. several prestack depth migration methods are proposed and unified to the synthetic source record migration method. these methods include plane wave migration with fourier finite difference ( ffd ) extrapolator, maximum energy plane wave migration and prestack migration with phase encoding of areal shot records
通過對本文提出的平面波傅立葉有限差分疊前深度偏移方法、最大能量面炮記錄疊前深度偏移方法和相位編碼面炮記錄疊前深度偏移方法的研究,試算和對比,提出了合成震源三原則,根據這些原則,提出了合成震源概念和合成震源記錄疊前深度偏移方法。 -
The synthetic source is the generalization of plane wave source, controlled illumination source, piecewise plane wave source and areal sources with phase encoding etc. by migrating the synthetic source record, the computational cost of the conventional areal shot record migration can be reduced by several times without significantly degrading the image quality
合成震源既包括了已有的平面波震源,也包括了控制照明震源,分段平面波震源和相位編碼震源。合成震源記錄疊前深度偏移方法是炮記錄偏移、平面波偏移、控制照明偏移和相位編碼面炮記錄偏移方法的推廣和統一形式。
