METHOD OF PROCESSING SEISMIC DATA FOR AVO OR AVOA CHARACTERISATION |
摘要 |
<p>The invention relates to a method of processing seismic data comprising a gather of seismic traces organised according to one or several acquisition parameters, each trace comprising a seismic signal defined by an amplitude as a function of time or depth, the method comprising the steps of: a) defining a base of elementary functions of the acquisition parameter(s), b) orthogonalising said elementary functions so as to define a base of orthogonal elementary functions c) for a given time or at a given depth, determining combination coefficients defining a combination of the orthogonal elementary functions, said combination being an estimator of a variation in the amplitude of the seismic signal as a function of the acquisition parameter(s).</p> |
