The synthetic seismic correlation of conversion S-wave for the interpretation of P-S wave seismic data was researched, and a method of making P-SV shear wave synthetic seismic record was proposed. According to deduction and statistics, pseudo P-S wave sonic log can be gotten by the P-wave sonic plus S-wave sonic, and good pseudo reflection coefficient of P-S wave can be gotten. Then, synthetic P-S seismic record can be made by conventional ways, and a synthetic P-S seismic record with correct time and approximate amplitude can be obtained. The method is characterized by simplicity. The application results of real data proved the validity and the foreground of the method.
