Abstract

En holdekilesåmmenstilling for forankring av et underjordisk brønnverktøy, slik som en pakning eller broplugg, langs den indre veggen av en ledning, slik som et fdringsrør, mot bevegelser i minst en retning. Etter som en rekke av radielt innret-tede holdekileelementer beveger seg fra tilbaketrukkede til ekspanderte posisjo-ner, er en kontinuerlig radiell innoverpressende forspenning påført mot holdekileelementene for å tillate at holdekileelementene beveger seg til den ekspanderte posisjonen i et vesentlig enhetlig ekspansjonsplan. Et underjordisk brønnverktøy innbefatter en elastomerisk tetning og holdekilesammenstilling.
