COMMON CONVERSION POINT GATHERING AND TIME-VARIANT STATIC CORRECTION

  • When the velocity ratio between compressional wave and shear wave is fixed, the horizontal location of conversion point of each sample in a trace is different, so the traditional method of trace gathering can only gather the common conversion points(CCP) of a certain depth, which cannot guarantee that all the samples' conversion points are at the same location. In this paper,the authors present a new method for CCP binning, and the CCP gather obtained from this method is a really CCP gather in which the projection of all samples' conversion points are at the same location.Based on this method, a time-variant short-wavelength static correction method for converted waves is proposed and the real data processing results prove the method feasible and effective.
