SEISMIC DATA PROCESSING TECHNIQUE Russian patent published in 2008 - IPC G01V1/30 

FIELD: measuring techniques; seismic data processing techniques.

SUBSTANCE: seismic data processing technique is based on obtaining a short term seismic section in the investigated earth layer and mapping it in the form of seismic paths. From the map, we can determine characteristic dimensions of local irregular geological objects, which are subject to investigation, and corresponding dimensions of the sliding window for calculations on the seismic section, which covers the stated objects, in coordinates of seismic time t (ms) and distance x (m), in the range for which displacement of the window on the profile in the displacement cycle with the given x coordinate and seismic time, t interval: we can determine the local form of the wave packet of reflected, diffracted and scattered waves, form a digital matrix of the stated local wave packets in the range of the investigated seismic section. The dynamic characteristics, in particular spectral and energy characteristics are determined from the obtained digital matrix of local wave packets. Reflecting properties of the investigated earth layer are determined from these characteristics.

EFFECT: increased information content of the results of processing intratelluric seismic data when investigating complex heterogeneous media of the Earth's crust and the upper mantle; increased effectiveness of seismic exploration.
