Abstract

System og fremgangsmåte til regulering av strømmen fra en petroleumproduserende gassløftebrønn der et borehull trenger gjennom minst to rommessig adskilte geologiske produksjonssoner og har en foring som strekker seg fra brønnhodet gjeimom borehullet og inn i begge de nevnte rommessig adskilte produksjonssoner og med minst to rørstrenger som strekker seg parallelt langs det indre av foringen fra brønnhodet og der den første rørstreng strekker seg til området ved den første av de nevnte rommessig adskilte produksjonssoner og den aimen rørstreng strekker seg inn i området ved den annen av de nevnte produksjonssoner. Systemet innbefatter en gassløfteventil som er innkoblet i hver av rørstrengene der en første ventil ligger i området ved den første produksjonssone og en andre ventil ligger i området ved den andre produksjonssone, en enkel kilde for gass under trykk tilsluttet foringen ved brønnhodet og for å danne en kilde for løftegass, og anordninger for uavhengig innstilling av størrelsen på den strømningsregulerende åpning i hver av de første og andre gassløfte-ventiler for å styre produksjonen av fluider fra hver av de nevnte første og andre produksjonssoner.
