Abstract

En brønntrykkisoleringsanordning (200) er plassert i en brønn og har et tettingselement som kan bli aktivert for å tette mot en indre overflate av et omkransende rør. Straks den er satt begrenser en kuleventil (260, 216) i anordningen (200) oppoverrettet fluidkommunikasjon gjennom anordningen (200), og en annen kuleventil (270 217) i anordningen kan begrense nedoverrettet fluidkommunikasjon gjennom anordningen (200). Disse kuleventilene kan ha oppløsbare kuler (260, 270) beregnet for å gå i oppløsning i brønnforhold etter ulike tidsperioder. For å underlette utplassering av anordningen (200) i en horisontal seksjon av brønnen har anordningen (200) et antall ruller (290) plassert på en fjern ende. I tillegg har anordningen (200) en ring (280) anordnet om legemet (210) mellom den fjerne legemsdelen og en tilstøtende legemsdel. Ringen (280) har en utvendig diameter som i det minste er større enn diameteren til den tilstøtende legemsdelen for å underlette pumping av anordningen (200) i brønnen.
