三维F－K域DMO方法及应用效果

3-D DMO ALGORITHM IN F-K DOMAIN AND APPLICATION

在常速情况下，从三维时距方程出发，通过倾角代换，将三维倾角时差分裂为两个正交方向上的二维倾角时差，然后在这两个正交方向上分别做一次二维倾角时差校正，便可达到三维倾角时差校正的目的．应用实例表明这种三维ＤＭＯ分裂方法是切实有效的．

Provided that the velocity is constant,3-D dipmoveout is split into 2-D dipmoveout by use of dip replace in orthogonal direction,which bases on 3-D time distance equation.It proves by satisfactory effect of real data Processing that the 3-D DMO splitting algorithm presented in the paper is valid.
