Method for plotting dynamical images with use of controlled directed analysis of seismic signals with non-linear delay function

摘要

The invention relates to means of applied geo-physics, in particular to methods for processing seismograms and plotting seismic cuts to obtain dynamical images with high resolving capacity at search and survey of fields of minerals, in particular of oil and gas. Method for plotting dynamical images with use of controlled directed analysis of seismic signals with non-linear delay function includes use of seismic data of systems of multiple observations, grouping those to seismograms by common for those characteristic, inclusion of static corrections, formation of bases for collection of regular reflected waves, determination of set of non-linear delay functions in time windows, formation by values of non-linear delay functions of collection axes, implementation of static evaluation of axes of collection in slide window to exclude non-inphase collection, determination of probability of inphase collection and its account at calculation of central axis of slide window, repetition of those operations for other non-linear delay functions and obtaining most probable total signal from all non-linear delay functions. The invention makes it possible to plot dynamical images with high resolution ability and to obtain detailed physical-geological models of prospective oil-gas bearing objects to improve effectiveness of prediction of deposits of oil and gas.
