Abstract: In the process of accurate interpretation of multi-wave seismic data to solve the problem of multi-wave information
recognition. Based on the techniques of elastic wave forwarding，aiming at the reservoir geological model of some oil field
exploration area，we use the high-order staggered-grid difference technology to simulate many shots seismic records of the
nonzero offset shot gathers，implement the multi-wave seismic data processing to acquire the CMP of P wave and converted
wave，NMO trace gathers of CCP prestack including AVA information，and superposition profiles. Based on the AVA calculation
of the model，the layer parameters of the model，and the forwarding wave fields relation of the P-S wave，we also compare，and
research the corresponding relation between the P wave and the converted wave. The results of analysis show that the simulation
results and AVO analysis results are consistent. The significant wave field differences of between P wave and converted wave
in same reservoir are existed，which are helpful to recognize and interpret the multi-wave information in this area，and make
use of the multi-wave data to provide the important guiding significance for the reservoir prediction.
