发明名称 Wellbore system with retrievable valve body
摘要 A system for inserting injection fluid into a stream of hydrocarbon fluid flowing through a wellbore formed in an earth formation is provided. The system comprises a production conduit for conveying the stream of hydrocarbon fluid through the wellbore to the earth surface, the conduit being provided with at least one valve chamber that is suitable to receive a retrievable valve body therein, the valve body including a valve that is controllable via an electric circuit connected to surface control equipment so as to move the valve between an open position thereof whereby the valve provides fluid communication between the stream and a fluid injection channel extending in the wellbore, and a closed position thereof whereby the valve prevents fluid communication between the stream and the fluid injection channel, wherein the electric circuit comprises an inductive coupler including a primary coil provided within the production conduit and a secondary coil provided within the valve body. The electric circuit comprises an inductive coupler including a primary coil provided at the production conduit and a secondary coil provided at the valve body.
