本文提出利用τ-p变换,使反射波记录上被强烈干扰的折射波得到突出和加强,从而求准静校正量的方法。使用这种方法可以方便地解决转换波勘探中复杂的静校正问题。

In ordinary reflection seismogram, the refraction wave was strongly interfered. But by using i-p transformation,the refraction recorded could be enhanced and thuswise the static correction could be performed with the data provided by the refraction. Based on what is mentioned above,a technique of making static correction with enhanced refraction by τ-p transformation was put forward. With this technique recommended, the hard nut of making static correction in converted wave exploration could easily be cracked.
