ASSESSMENT METHOD low-frequency resonant NOISE EMISSION GEODYNAMIC

摘要

A method of evaluating the low-frequency resonance emission (EME) geodynamic noise comprising seismic measurements and the subsequent processing of the measurement data, characterized in that the EME assay is performed directly on a temporary cut seismic data method common depth point (CDP), the method comprising the following successive operations: 1 ) obtaining CDP seismic data; 2) selecting a portion of the time section CMP; 3) elimination of energy regular waves observed time section and CDP wavefield decomposition characterizing different energies by the two-dimensional adaptive filtering; 4) perform wavelet transformation data providing expansion and geodynamic noise filtering in different frequency bands and the energy plotting frequency dependencies and wavelet transform coefficients; 5) Mapping EME anomalies for each reflector of individual seismic lines and comparing it with the structural map of the test horizon.
