STUDY OF WAVE FIELD SPECTRAL CHARACTERISTICS OF THE MODEL DATA WITH WAVELET TRANSFORM

(Butorin A.V. )

Frequency-time analysis of seismic data with the wavelet transform based algorithm is increasingly being used in the workflow of the wave field interpretation. The study described in the article, describe the appearance of anomalies of the wavelet spectrum on the example of simple models. Understanding the reason of anomalies and study of their changes enables to determine the main directions in the use of the wavelet transform.......

COMPARATIVE ANALYSIS OF SPECTRAL INVERSION METHODS ON THE MODEL DATA

(Butorin A.V. Krasnov F.V. )

The article describes different methods of spectral decomposition on model seismic traces. The main methods are considered: windowed Fourier transform, continuous wavelet transform and algorithms of spectral inversion. /4s a result of performed study it was shown that spectral inversion methods based on the solution of the problem of approximation of an input alignment a library of wavelets with the help of Lp-regularization, provide a much more accurate spectral representation of the signal.......
