Abstract

En fremgangsmåte for å behandle seismiske refieksjonstrascr som registrere for variable forskyvninger, der en parabolsk eller hyperbolsk Radon transformasjon anvendes på oppsamlinger d(t,x) av seismiske traser med felles midtpunkt og normal utvandring (NMO), slik at hver oppsamling d(t,x) omformes til et diagram |i(T,q) på hvilket hver seismisk hendelse av d(t,x) fokuseres på et energikonsentrasjonsområde. Hendelsen som fokuseres på hvert av energikonsentrasjonsområdene for diagrammet )i(T,q) bli så rekonstruert i lineær form i et diagram D(t,x2) ved hjelp av stakking langs en rett linje som avsøker et vindu som er sentrert på det tilsynelatende punktsenter for energikonsentrasjonsområdet det er tale om, og som dekker hele nevnte område. Fremgangsmåten er nyttig for geofysisk behandling og særlig for å bestemme avskjærings (Ro) og gradient (G) størrelser ved hjelp av amplitude-i-forhold-til- forskyvninganalyse (AVO).
