Abstract:

Geostatistic method is an effective approach in studying the distribution of spatial variation including regional variation,variation function,kriged estimate.In seismic data processing,static correction,superficial velocity,time difference,dip angle and curved ray may result in errors in interval velocity calculation.The geostatistic method could find the internal space variation regularity of interval velocity,restrain random error and improve signal noise ratio,thus correcting the error of seismic interval velosity.
