Abstract

Denne oppfinnelsen vedrører en sko for brønnhullsfôringsrør og en fremgangsmåte for å plassere brønnhullsfôringsrør i et brønnhull. I én utførelsesform vises en sko (30) som inkluderer et rørmessig utvendig legeme (32) som er koplet til et brønnhullsfôringsrør (28) og et rørmessig innvendig legeme (36) plassert innenfor det utvendige legemet og koplet til rør (38) for fluidtilførsel. Et generelt ringromformet strømningsområde (44) defineres mellom legemene som er i selektiv fluidkommunikasjon med brønnhullet (10), for returstrømmen av fluid fra brønnhullet gjennom en strømningsåpning (62) i det utvendige legemet, langs skoen og inn i et ringrom (46) definert mellom brønnhullsfôringsrøret og røret for fluidtilførsel. En ventilsammenstilling (40) av skoen har et aktiveringselement (92) plassert innenfor det innvendige legemet, og en strømningsregulator (96) for selektiv lukking av strømningsåpningen. En kule (98) anvendes for å ytterligere forhindre fluidstrømning gjennom det innvendige legemet inn til brønnhullet. Eksponering for aktiveringselementet mot fluid ved et første fluidtrykk forårsaker da at aktiveringselementet beveges til en aktiveringsposisjon hvor strømningsregulatoren lukker strømningsåpningen. Eksponering for fluid ved et andre fluidtrykk høyere enn det nevnte første fluidtrykket åpner på nytt fluidstrømning fra det innvendige legemet til brønnhullet. 1
