Abstract

Rørhenger (2) for å legge til rette for produksjonsrør-ringsromstilgang inkluderende et legeme til en rørhenger (2) som har en midtstilt boring, en skifteventil (28) glidbart montert til legemet til rørhengeren (2), og i det minste en ringroms-tilgangsboring (20) gjennom rørhengeren (2) som tillater fluidkommunikasjon mellom den midtstilte boringen og et ringrommet definert mellom en produksjonsrørstreng og et brønnhull eller foring via legemet til rørhengeren (2) og skifteventilen (28). Skifteventilen (28) kan være glidbart bevegelig mellom en åpen og en stengt posisjon. Rørhengeren (2) kan videre inkludere et spor (18) omsluttet med et fyllmateriale (22), sporet (18) sørger for kommunikasjon mellom et flertall av små ringroms-boringer (10,12) og en stort ringroms-boring (20).
