dispositivo de controle de fluxo, e métodos para operar um dispositivo de controle de fluxo, para controlar o fluxo de fluido de um reservatório de óleo e/ou gás, e para controle reversível sensível á temperatura do fluxo de fluido em produção de óleo e/ou gás, e, aparelho para controle reversível sensível á temperatura do fluxo de fluido em produção de óleo e/ou gás.

摘要

A method for reversible temperature sensitive control of the flow of fluid in oil and/or gas production, involves a control device or an autonomous valve operating by the Bernoulli principle and includes a moveable disk or body provided within a housing for opening and closing the valve, involving use of the Curie-effect in order to position the body in a preferred position within the housing at a temperature below a certain, preferred transition or Curie temperature. An apparatus for reversible temperature sensitive control of the flow of fluid in oil and/or gas production including a control device or an autonomous valve operating by the Bernoulli principle and including a moveable disk or body provided within a housing for opening and closing the valve, the body and housing including a ferromagnetic material having a certain, preferred Curie temperature, the temperature being selected in order to position the body in a preferred position in the housing during installation or operation.
