摘      要：In the process of accurate interpretation of multi-wave seismic data,we wanted to solve the problem of multi-wave information *** on techniques of elastic wave forwarding,targeting the geological model of a reservoir of an oil field exploration area,we used a high-order staggered-grid difference technology to simulate many shots of seismic records of nonzero offset shots,implemented multi-wave seismic data processing to acquire the CMP of P waves and converted waves,NMO traces of CCP pre stacks,including AVA information and superposition *** on the AVA calculation of the model,the layer parameters of the model and the forwarding wave field relations of the P-S wave,we also compared and studied the correspondence between P waves and converted *** results of our analysis show that the results from simulation and from the AVO analysis are *** wave field differences between P waves and converted waves in the same reservoir were found,which are helpful in recognizing and interpreting the multi-wave information in this *** made use of the multi-wave data to provide the important guidelines for reservoir prediction.
