Abstract

Beskyttende hylse (18) for montering nmdt et borerør (12) som benyttes for å bore en brønnboring i en underjordisk formasjon, idet hylsen danner kontakt med innsiden av en brønnboring eller foring når borerøret avbøyes fra sentrum i boringen eller foringen, for å beskytte foringen eller boringen mot kontakt med borerøret eller skjøtene i dette under rotasjon av borerøret. Hylsen er laget av et elastomerisk materiale og omfatter et sylindrisk forsterkningsbur innleiret i veggen til hylsen for å øke dens styrke, og omfattende sliteputer i innbyrdes avstand, fastgjort til burveggstrukturen, idet sliteputene omfatter et materiale som har større abrasjonsmotstand enn hylsematerialet. Sliteputene er innleiret i det elastomeriske materialet i hylseveggstrukturen og forløper gjennom den sylindriske veggen til hylsen, til i nærheten av en ringformet ende på hylsen nær aksiallageret, til en posisjon der sliteputene utsettes for slitasje når det opptier belast- ninger, for derved å øke brukstiden til hylsen.
