Title: Fremgangsmåte for fjerning av harmonisk støy fra innsamlede data
Inventor: JEFFRYES BENJAMIN PETER
IPC: G01V1/143
Filed: 2003-04-04
Abstract: En fremgangsmåte for seismiske undersøkelser omfatter de trinn å aktivere vibratoren eller hver vibrator i en første vibratorgruppe ved en tid TO, og deretter å aktivere vibratoren eller hver vibrator i en annen vibratorgruppe ved tid Tl som tilfredsstiller TO < Tl < TO + Sl + L, hvor Sl er sveipetiden for den første vibratorgruppe og L er lyttetiden Minst én av den første vibratorgruppe og den annen vibratorgruppe omfatter minst to vibratorer. Den første gruppe og den annen gruppe med vibratorer kan være den samme gruppe, eller de kan være forskjellige grupper. Denne fremgangsmåten gjør det mulig å redusere den tid som er nødvendig for å fullføre en seismisk undersøkelse sammenlignet med de tidligere kjente samtidig skudd"- og "glidesveipskyte"-teknikker. I et tilfelle hvor den første gruppe og den annen gruppe med vibratorer er forskjellige, kan fremgangsmåten videre omfatte å aktivere vibratoren eller hver vibrator i den første vibratorgruppe ved en tid T2, hvor Tl < T2 < Tl + S2 + L, og hvor S2 er sveipetiden for den første vibratorgruppe, og så å aktivere vibratoren eller hver vibrator i den annen gruppe ved en tid T3 hvor T2 < T3 < T2 + Sl + L, og hvor T3 - T2 # Tl - TO. Den varierende tidsforsinkelse mellom et skudd i den første vibratorgruppe og det tilsvarende skudd i den annen vibratorgruppe betyr at harmonisk støy vil opptre ved forskjellige tider i skuddregistreringene slik at støyen kan elimineres ved på passende måte å kombinere skuddregistreringene.
