Abstract

Autonom innstrømningskontrollinnretning (4) for et produksjonsrør (2) i en hydrokarbonbrønn (12), hvor innstrømningskontrollinnretningen (4) omfatter et innstrømningsrør (42) som er forsynt med flere pakninger (41, 41', 41", 41'") som er anordnet med innbyrdes aksiell avstand langs et parti av innstrømningsrøret (42), hvor pakningene (41, 41', 41", 41'") er fluidtettende settbare mot en brønnhullsvegg (121) for tildanning av adskilte innstrømningsseksjoner (43, 43', 43") i et ringrom (3) som omkranser innstrømningskontrollinnretningen (4); og det i hver innstrømningsseksjon (43, 43', 43") er anordnet minst en vannavstengningsanordning (44) med en ventilelementsammenstilling (440) som er omstillbar mellom en første, åpen stilling (I) og en andre, lukket stilling (II), idet ventilelementsammenstillingen (440) i den første stillingen (I) tildanner en fluidstrømningsvei (448) ved at et forskyvbart ventilelement (442) holdes i en avstand fra et ventilsete (441) ved hjelp av minst ett vannløselig avstandselement (443).Autonomous inflow control device (4) for a production tube (2) in a hydrocarbon well (12), the inflow control device (4) comprising an inflow tube (42) provided with several gaskets (41, 41 ', 41 ", 41'") which are spaced apart along a portion of the inflow tube (42), the gaskets (41, 41 ', 41 ", 41'") being fluid-sealable against a wellbore wall (121) for forming separate inflow sections (43, 43 ', 43 ") in an annulus (3) encircling the inflow control device (4); and in each inflow section (43, 43 ', 43") at least one water shut-off device (44) is provided with a valve element assembly (440) which is adjustable between a first, open position (I) and a second closed position (II), the valve member assembly (440) forming in the first position (I) a fluid flow path (448) by holding a slidable valve member (442) at a distance from a valve seat (441) ) using at least one water-soluble spacer (443).
