摘要

flow control device, and methods for operating a flow control device, for controlling fluid flow from an oil and / or gas reservoir, and for temperature-sensitive reversible control of fluid flow in oil and / or gas production. and, reversible temperature sensitive fluid flow control apparatus in oil and / or gas production is described a method for reversible temperature sensitive fluid flow control in oil and / or gas production involving a device or a stand-alone valve (2) operating on the Bernoulli principle and comprising a disk or movable body (9) provided within a housing (4) for opening and closing said valve (2), involving the use of curie effect. for positioning said body (9) in a preferred position within said housing (4) at a temperature below a given transition temperature or curing temperature. Also described is an apparatus for reversible temperature-sensitive control of oil and / or gas producing fluid flow comprising a control device or an autonomous valve (2) operating on the Bernoulli principle and comprising a disk or movable body ( 9) provided within a housing (4) for opening and closing said valve (2), said housing (9) and housing (4) comprising a ferromagnetic material having a certain preferred curing temperature, said temperature being selected from to position the body (9) in a preferred position in the housing (4) during installation or operation.
