Abstract:Resampling is a method for producing a high-resolution seismic section. This method consists of the following steps:deriving the layered relative acoustic impedance data from an usual stackedlow-frequency seismic section with the use of Walsh function·denser resampling of the acoustic impedance data compressing the wavelets along time axis on the condition that their wadeforms remain unchanged producing a high-resolution section by combining the resampled acoustic impedance data with compressed wavelets to form seismic traces.The processing results of modeling and real data prove that’the resampling method improves resolution greatly,without noise increased. The high resolution seismic section is very helpful to the discovery of minor faults,thin lens and pinch;therefore it will find wide application in thin reservoir research.
