Abstract

I en anordning for styring av en fluidproduksjonsbrønn kan en styreanordning (D), slik som en strupeventil som er plassert nedihulls, drives valgvis av første og andre driverutstyr (2, 3). Det er anordnet første og andre effektforsyningsutstyr (A, 13) og første og andre styringskanaler (Kanal A, Kanal B) for styresignaler for det første og andre driverutstyr, idet det er ordnet slik at dersom den ene effektforsyning svikter kan vedkommende driverutstyr (2, 3) drives ved hjelp av den annen effekt-forsyning. Det er anordnet første og andre utstyr (DEM lA, DEM 1B) for å rute styresignaler på henholdsvis den første (A) og andre kanal (B) til det første og andre driverutstyr (2, 3), idet rutings-utstyret er slik sammenkoblet at i tilfellet av en feil blir styresignaler fra den andre kanal (B) rutet via det første rutingsutstyr til det andre driverutstyr (3) og/eller styresignaler fra den første kanal (A) rutet via det andre rutingsutstyr til det første driverutstyr (2).In a device for controlling a fluid production well, a control device (D), such as a throttle valve located downhole, may optionally be driven by first and second driver equipment (2, 3). First and second power supply equipment (A, 13) and first and second control channels (Channel A, Channel B) for control signals for the first and second driver equipment are provided, so that if one power supply fails, the respective driver equipment (2, 3) Powered by the other power supply. First and second equipment (DEM 1A, DEM 1B) are provided for routing control signals on the first (A) and second channel (B), respectively, to the first and second driver equipment (2, 3), the routing equipment being so interconnected that in the event of an error, control signals from the second channel (B) are routed via the first routing equipment to the second driver equipment (3) and / or control signals from the first channel (A) routed via the second routing equipment to the first driver equipment (2) .
