Abstract

En metode for evaluering av borehullintegritet inkludert introduksjon av et bor til en overflate av en fôring innebefattende et ringrom, omsluttende boret i et hus som hydraulisk isolerer overflaten, boring gjennom fôringen, observasjon av trykket på væsken og bruk av trykkobservasjonen og borkroneposisjonen til å vurdere om det finnes en defekt og lokalisering av defekten. Apparat for evaluering av borehullintegritet inkludert en sonde omfattende et bor, hvor sonden er hydraulisk isolert fra borehullet, en ventil som innebefatter boret, en trykkmåler for måling av trykket i væsken inni huset, en trykkmåler for måling av trykket i systemet utenfor huset og utstyr til sammenligning av trykkmålingene og posisjonen til boret og evaluering av en forekomst av og en posisjon for defekten.
