In order to remove the residual static moveout of seismic data in mountainous area, this paper recommends a new method which automatically computes residual static corrections (or static corrections) by making use of first arrivals before NMO correction.

• 为消除山区地震资料中的剩余静态时差,本文提出一种利用初至波在动校前自动计算剩余静校正量(或静校正量)的方法。
