Abstract

Fremgangsmåte til bestemmelse av en hastighet til lyd som beveger seg i et fluid i et borehull, hvilken fremgangsmåte inkluderer: plassering av et logge-instrument i borehullet, idet instrumentet inkluderer en første akustisk transduser og en annen akustisk transduser som er forskjøvet fra hverandre i avstand til en vegg i borehullet, den første transduser er tilpasset til å sende ut en første akustisk bølge som reflekteres av veggen og den annen akustiske transduser er tilpasset til å sende ut en annen akustisk bølge som reflekteres av veggen; bestemmelse av en differanse mellom en gangtid for den første akustiske bølge og en gangtid for den annen akustiske bølge; og beregning av hastigheten ved bruk av differansen og forskyvningen.
