Abstract

En pakning for en brønn beskrives. Pakningen omfatter et tetningselement og et tetningssetteapparat. Tetningssetteapparatet er bevegelig i forhold til tetningselementet i innsettingsretningen for å påføre en settekraft til tetningselementet for å bevege tetningselementet fra en innkjøringskonfigurasjon og til en satt konfigurasjon i hvilken tetningselementet i bruk danner en kontakttetning med en ledningsvegg. I bruk er pakningen anordnet slik at i den satte konfigurasjonen vil en trykkforskjell over pakningen som skaper en kraft i innsettingsretningen, øke settekraften som påføres ved hjelp av tetningssetteapparatet på tetningselementet for å bibeholde tetningen.
