Abstract
En Bonelsoleringsanordnlng (13) er tilvelebragt som gir mulighet for valgvls kommunikasjon av fluid mellom en arbeldsstreng (29) og en eller flere underjordiske soner. Fluldtrykk-aktlvlserte ekspansjonspaknlnger (15, 17) kan anbringes på ethvert ønsket sted Inne l en arbeldsstreng uten hensyn til plasseringen av andre ekspansjonspaknlnger, som tillater maksimal bruker- flekslbllltet og tilpasning av sonelsolerlngs- anordnlngen på stedet. Hver ekspansjonspaknlng Innbefatter en rotasjonskopllng for å gl mulighet for rotasjon av arbeldsstrengen under den Innførende og tettende drlftstllstand. En låsemekanlsme er anordnet for å hindre for tidlig eller utilsiktet ekspansjon.
