METHOD TO PROCESS SEISMIC DATA USING DISCRETE WAVELET TRANSFORM

摘要

FIELD: mining. ^ SUBSTANCE: in method to process seismic data using discrete wavelet transform, including provision of seismic data in the form of set of seismic roads, each of initial seismic roads represented as vector of counts is exposed to discrete wavelet transform (M iterations) with subsequent decay (decomposition) of initial seismic signal into layers of detail dl(n) with various power and frequency characteristics; each of specified layers of detail dl(n) is analysed by their target value with account of solved seismic task, afterwards valuable separate layers of detail are selected in wavelet transform of initial seismic signal to build their partial sums for further processing and interpretation of seismic data. ^ EFFECT: making it possible to analyse seismic data with localisation of signal features in wavelet-frequency area with improved quality of separation of signal component features in space-time coordinates, with division of wave fields into separate components and increased signal-noise ratio. ^ 5 dwg
