Abstract
Det er vist en pakning som anvender påført trykk til å sette kilene (86) og innlede en kraft på tetningselementene (46, 48, 50, 52). Trykkraften som påføres tetningselementene beveger kompo- nentene over tetningselementene og tillater det tilgjengelige hydro- statiske trykk i brønnboringen å skape en motsatte kraft på tetningselementene for å sikre at de settes riktig. Tetningselemen- tene (46, 48, 50, 52) er montert direkte på pakningslegemet, og eliminerer således en lekkasjebane fra fluidtrykk-innløpsporten (42) som er beliggende under tetningselementene på paknings- legemet. Forskjellige låseringer (74, 142) holder pakningen i satt tilstand for å unngå dannelse av forsterkningskrefter på tetnings- elementene fra påførte eller innførte trykk fra over eller under tetningselementene. Bevegelse av legemet er ikke nødvendig for å oppnå setting av denne pakningen. Ved anvendelse med lavt hydrostatisk trykk, kan ringrommet settes under trykk for å medvirke til å oppnå det nødvendige pakningstrykk. Det hydro- statiske trykk er fortsatt tilgjengelig som en pakningskraft selv når trykket under pakningselementet avtar etterhvert som reser- voaret tømmes. Pakningselementet, som er montert direkte på pakningslegemet, eliminerer lekkasjebaner bak dette, samtidig som pakningselementet settes ved hjelp av motsatte krefter, dvs hydraulisk nedenfra og hydrostatisk ovenfra.
