本文探讨了用沙赫公式求取层速度时,以迭加速度V_s代替V_NMO的可行性,并用模型试验算出了误差。文末还提供了一应用实例。

In this paper, the posibilities of the substitution of the stack velocity for the V_NMO velocity in the interval velocity extractions by shah formula were discussed. The errors were given by model experiments. An example about the applicatino of this method was presented.
