Abstract
En fremgangsmåte for strømningsstyring samt en selvjusterende ventil eller strømningsstyreanordning, spesielt anvendelig i et produksjonsrør for produksjon av olje og/eller gass fra en brønn i et olje- og/eller gassreservoar, hvilket produksjonsrør inkluderer et nedre dreneringsrør som fortrinnsvis er delt i minst to seksjoner som hver inkluderer en eller flere innstrømningsstyreanordninger som setter den geologiske produksjonsformasjonen i forbindelse med strømningsrommet til dreneringsrøret. Fluidet strømmer gjennom et innløp eller åpning (10') og videre gjennom en strømningsvei hos styreanordningen (T) som passerer et ikke-skiveformet bevegelig legeme (9') som er konstruert for å bevege seg i forhold til åpningen av innløpet og dermed reduserer eller øke gjennomstrømningsarealet (A2) ved å utnytte Bernoulli-effekten og stagnasjonstrykk skapt over legemet (9'), idet styreanordningen, avhengig av fluidets sammensetning og dets egenskaper, automatisk justerer fluidstrømmen basert på en forhåndsdefinert strømningsdesign.
