Abstract

Abstract:

Log datarestricted wave impedance inversion technique is based on convolutional model.Because of misunderstanding its theory foundation,this method was misused to obtain high-resolution impedance profile or to improve seismic profile resolotuion.The theoretic modeling results of log data-restricted wave impedance inversion indicate that seismic inversion result has multiple roots.The similarity between seismic tracs does not mean the similarity between impedance series or reflection coefficient series.Coherent coefficient obtained from comparing synthetic seismic profile with original seismic profile can not be used as restricted condition to invert highresolution impedance profile or to improve seismic profile resolution in practical seismic data processing.

Key words: well-restricted, impedance, inversion, coherent coefficient, high-resolution
