前言地震波的传播速度是地震资料解释的基础,它直接影响地震勘探的精度。在地震勘探中获得速度资料有很多方法。目前大多是从多次覆盖资料中直接求取速度值的,即将反射同相轴(能量)转换成垂直入射时间和速度的关系,这种关系叫做速度谱。采用迭加的方法制作速度谱有两个途径:一是用给定的一系列速度值,对共反射点的时距曲线进行动校正并迭加;二是用给定的一系列动校正量△t,对共反射点的时距 Preface The propagation speed of seismic waves is the basis of seismic data interpretation, which directly affects the accuracy of seismic exploration. There are many ways to get velocity data in seismic exploration. At present, most of the data are directly obtained from the multiple speed values, the reflection of the events (energy) into the vertical incidence of time and speed of the relationship, this relationship is called the velocity spectrum. There are two ways to make the velocity spectrum by using the superposed method. One is to use the given series of velocity values ​​to make dynamic correction and superposition of the time-distance curve of the common reflection point. The second is to use a given series of dynamic correction △ t, the time point of the total reflection point
