Abstract：Along with the development of multi-component seismic exploration technique,multi-wave AVO analysis is paid widely attention to by the people in aspects identifying the reservoir characters and raising the successful rate of petroleum prediction.In accordance with the geologic feature and requirement of petroleum exploration and development in Xincheng area of northern part of Songliao basin,the paper carried out the study on identification of sand/gravel and volcanic gas-bearing reservoir in 3000m well depth and below of well-XS1 by multi-wave AVO analysis.First,based on the practical well data in the gas-bearing well interval,the paper built up multi-wave AVO model of sand/gravel and volcanic gas-bearing reservoir,created the feature of PP wave and PS wave on AVO gathers by forward simulation.On that basis,the multi-wave data processing and analysis are carried out on the seismic line passing through well-XS1,the result identified by the method for gas-bearing reservoir is consistent with the result of forward simulation and PS-wave AVO analysis has clear superiority to PP-wave in aspect of identifying gas-bearing reservoir.
