normal moveout

The stack method after normal moveout is not effective.

本文针对因存在噪音和信号比较弱 ,致使正常时差 (NMO)校正迭加方法难以奏效的问题 ,提出提高信噪比和增强反射信号同相轴连续性的共反射面元 (CRS)迭加方法 。

In view of the situation that normal moveout correction stack method could not work very well for the low signal to noise ratio, we give an enlarging common reflection surface stack method to raise signal to noise ratio and enhance reflect wave s continuity.

因此 ,针对因地震资料的信噪比较低而导致常规的正常时差校正叠加方法难以奏效的情况 ,提出了提高信噪比和增强反射波连续性的扩大反射面元叠加方法。
