Abstract：It is basic work for seismic data interpretation by using convolution model for making synthetic seismogram and then marking event.Building on the lmsis of verrical incident seismic wave by ordinary recurrence formula of reflection coefficients and having not consideyed variation of reflection coefficients with incident angle (or offset) by the recurrence formina,resulted quantity and polarity of reflection coefficients may have much difference with real data and easily resulted in errors in lithologic interpretation and event marking.The paper gave the recurrence formula of reflection coefficients in a non-zero offset condition by simplified Zoeppritz functions.Using recurrence formula can calculate the reflection coefficient sequence at different offset and on different gather and convolution of the resulted section with wavelet can obtain more accurate seismogram.Model test shows correctness of the method.
