Abstract

En fremgangsmåte er beskrevet for injisering av løftegass eller annet fluid i et produksjonsrør for en oljebrønn via en eller flere slitebestandige løftegassstrømningskontrollinnretninger nede i brønnen som hver omfatter: et rørformet ventilhus (1) omfattende en strømningspassasje (2) med en oppstrømsende (9) som er forbundet til et løftegasstilførselsrør og en nedstrømsende (10) som er forbundet til det indre av produksjonsrøret, et klaffventillegeme (3) som er svingbart forbundet til ventilhuset (1) og anordnet i strømningspassasjen (2), slik at når ventillegemet svinges til en åpen posisjon blir ventillegemet orientert vesentlig parallelt med strømningspassasjen og hvis ventillegemet svinges i den stengte posisjon, blir ventillegemet svingt vesentlig vinkelrett på strømningspassasjen og blir trykket mot et ringformet ventilsete (4) for derved å blokkere passasjen med luftgass gjennom strømningspassasjen (2), en ventilbeskyttelseshylse (5) som er skyvbart anordnet i strømningspassasjen (2) mellom en første posisjon vist på fig. 2, idet hylsen (5) strekker seg gjennom det ringformede ventilsete mens ventillegemet (3) er svingt i den åpne posisjon, for derved å beskytte ventillegemet og setet mot slitasje av fluksen fra løftegassen eller et annet fluid og en andre posisjon vist på fig. 1, hvor hylsen (5) strekker seg gjennom delen av strømningspassasjen (2) oppstrøms av ventilsetet (4) mens ventillegemet (3) blir svingt i den stengte posisjon, og en strømningsbegrenser (8) som former del av ventilbeskyttelseshylsen (5) som er dimensjonert slik at fluksen fra løftegassen som strømmer gjennom strømningsbegrenseren (8) frembringer en trykkforskjell som får hylsen (5) til å bevege seg mot den første posisjon.
