Abstract

En avtettende yttermantel (30) på en ekspanderbar brønnpakning (10) omfatter en rekke av vekselvis tykke (34) og tynne (32) ringformede partier som vil øke tetningskrefter og forebygge forplanting av sprekker eller revner i elastomerman- telen. Fastliming til bare deler av de underliggende spiler (28) samt en avsmalnende profil og avstand til et endefeste (46) medvirker til å fastholde mantelen i riktig stilling under nedføring og tilbakehenting, og til å minske sannsynlig- heten for utvikling av sprekker og/eller rifter.
