Abstract
En pakning som kan anvendes med en brønn inkluderer et elastisk tetningselement og et støtteelement. Det elastiske tetningselement er innrettet for radialt å ekspandere i respons til den langsgående kompresjon av elementet. Støtteelementet er i det minste delvis omgitt av tetningselementet og er innrettet til radialt å ekspandere med tetningselementet for å understøtte dette. Støttehylsen er vesentlig hardere enn tetningselementet.
