Abstract

Et apparat for å måle formasjonsresistivitet gjennom et ledende rør i en borebrønn presenteres. Apparatet omfatter en sonde innrettet til å beveges gjennom borebrønnen, der et flertall av spenningsmålingselektroder er anordnet med mellomrom på sonden. minst en strømkildeelektrode er anordnet på sonden. Alle elektrodene er innrettet til å opprette elektrisk kontakt med røret. Apparatet omfatter en digital spenningsmålingskrets styrbart koplet for å velge enkelte av spenningsmålingselektrodene og digitalt styrte strømkilder.
