摘要
The ability of seismic response to distinguish geologic phenomena depends on the resolution of seismic records.The resolution study in biphasic medium is useful to high resolution oil-gas and ocean seismic exploration technology.Combining the velocity and attenuation analysis,we studied the relationship between seismic exploration resolution and wave propagation length based on the BISQ model.The paper also analyzed the resolution changing in different medium parameter.The study indicates that: with the wave propagation dominant frequency smaller and the resolution is lower;with the permeability higher the resolution is relatively higher,with the coefficient of viscosity higher the resolution is relatively lower,with the jet length higher the resolution is relatively lower when else condition keep invariant.
