Abstract

Den foreliggende oppfinnelse angår generelt en produksjonssikringsventil (200) som er utformet for å styre fluidstrømning gjennom en produksjonsrørstreng (120). I ett aspekt er det tilveiebrakt en sikkerhetsventil (200) for innsetting i en brønn (100) nedenfor dets overflate. Ventilen (200) innbefatter et regulerings-stempel (205A)og et balansestempel (205B). Ventilen (200) er utformet for å forbindes med en kontrollenhet (150) på overflaten ved hjelp av en styreledning (145A) slik at reguleringsstempelet (205A) er aktiverbart mellom en første stilling og en andre stilling som respons på mottak av trykksatt fluid fra kontrollenheten (150) gjennom styreledningen (145A). Balansestempelet (205B) er utformet for å kompensere for hydrostatisk trykk i styreledningen (145A). Ventilen (200) kan ha en boring (260) gjennom seg, og reguleringsstempelet (205A) kan være utformet for utnyttelse av rørtrykk inne i ventilboringen (260) for å drive reguleringsstempelet (205A) mot den andre stilling.
