Abstract
SAMMENDRAG En fremgangsmåte for å prosessere seismiske data omfatter å identifisere verdien av en første parameter assosiert med en hendelse i et første sett av seismiske data. Verdien av en andre parameter assosiert med en korresponderende hendelse i et andre sett av seismiske data fremskaffes deretter ved bruk av minst én oppslagstabell. Den første parameteren kan for eksempel være PP-gangtid med det første datasettet som et rå-PP-datasett, og den andre parameteren kan for eksempel være PS-gangtid med det andre datasettet som et rå-PS-datasett eller refleksjonsdybde. Oppfinnelsen gjør det mulig å identifisere par av korresponderende PP- og PS-hendelser i rådatatraser. Oppslagstabellen(e) fremskaffes ved bruk av en antatt modell for propageringshastigheten av akustisk energi i jorden. Resultatene av fremgangsmåten kan benyttes i kvalitetskontroll, eller kan benyttes for å korrigere hastighetsmodellen.SUMMARY A method for processing seismic data comprises identifying the value of a first parameter associated with an event in a first set of seismic data. The value of a second parameter associated with a corresponding event in a second set of seismic data is then obtained using at least one lookup table. For example, the first parameter may be PP run time with the first data set as a raw PP data set, and the second parameter may be, for example, PS run time with the second data set as a raw PS data set or reflection depth. The invention makes it possible to identify pairs of corresponding PP and PS events in raw data mattresses. The look-up table (s) is obtained using an assumed model for the propagation rate of acoustic energy in the earth. The results of the method can be used in quality control, or can be used to correct the velocity model.
