- NMO动校正normal moveout
- 常规2次NMO动校是假定炮检距与深度比值小,并且射线为直线。The conventional 2~(nd) order NMO assumes a small offset-to-depth ratio and straight raypaths.
- 它的基本思路是,当反射界面倾斜时,动校正分为两步来实现:(1)先进行与倾角无关的动校正,把 t 校正到 t_n,称之为 NMO;According to its principle,when reflector is dipping,dynamic correction is accomplished in two steps:(1)NMO correction,which is independent of dip and corrects t to t_n;
