Application of Wellhead Operation Control Valve in Well Servicing Operations
In offshore oil field workover operations,after dismantling the Christmas tree and attempting to lift the production string,complex situations such as the string being stuck and unable to move,and the inability to establish circulation during well flushing are often encountered.To address this situation,a wellhead operation control valve has been developed.This device is installed on the wellhead tubing hanger,which can assist in well control,establish circulation and steel wire and cable operation channels,and avoid the problem of hydraulic control pipeline reconnection affecting the pressure test of the ram blowout preventer.The on-site application shows that the wellhead operation control valve is easy to operate and can effectively solve the complex situation mentioned above,with good prospects for promotion and application.
