Abstract

En utvidbar eksentrisk rømmer for plassering i en borestreng opphulls for en tradisjonell borekrone. Rømmerbladet (22) er aktivert med borefluidtrykk for radialt å strekke seg ut til en utboringsdiameter større enn en gjeimomføringsdiameter. Rømmerlegemet (12) er utformet for å ha en eksentrisk ytre overflatekonfigurasjon for å oppta rømmerbladet i dette. Rømmerbladet fimgerer som en stempelarm i reaksjon på borefluidtrykk og beveger seg langs en aksel (28) forankret i et fremspringsområde (18) som tilformer en eksentrisitet i den ytre overflatekonfigurasjonen av legemet. Rømmerbladet har en ytre kantkonfigurasjon som posisjonerer skjæreme (24) på dette for å hindre disse fiia å danne anlegg med et foringsrør i et brøimborehull ved anvendelse.
