摘要： A valve arrangement for a wellhead of a hydrocarbon well comprises a valve for mounting in a port of a wellhead, and an actuator device for actuating the valve to move to an open position. The actuator device comprises a housing having a through channel extending between a first end, at which the valve is mounted, and a second end. The housing comprises at least one first port that leads into the through channel. The actuator device further comprises an actuator rod that is movably arranged in the through channel and configured to open the valve by the actuator rod being movable between at least a first position and a second position, and a control device arranged to control the movement of the actuator rod.

摘要： A gas lift valve for use in a hydrocarbon well includes an elongated valve housing including an inlet port for receiving a fluid from an annulus of a hydrocarbon well, and an outlet port for delivering the fluid to a production tubing of the hydrocarbon well, and an elongated, internal valve body, which is movable along a longitudinal, central axis of the valve housing between a first end position and a second end position. In the first end position, a sealing surface of the valve body is in sealing contact with a valve seat surface of the valve housing prohibiting the fluid to flow from the inlet port to the outlet port, and in the second end position the sealing surface is separated from the valve seat surface allowing the fluid to flow from the inlet port to the outlet port. The outlet port is positioned at a terminal end of the valve housing.

摘要： The present invention relates to an apparatus for monitoring physical parameters in an oil and/or gas well, the apparatus being connectable to a wellhead of the oil and/or gas well. The apparatus comprises a flange assembly configured with a through bore and an end termination, in which through bore a sensor and associated electronics are arranged. The sensor, including a first electronic circuitry, is connected to a second electronic circuitry via transmission devices that are passed through a pressure-tight element arranged in the through bore. The invention also relates to a wellhead for use with an oil and/or gas well with a plurality of casings defining a plurality of annili. The wellhead is configured with a plurality of through-holes, each leading into a respective annulus of the well, and each through-hole is connected to an apparatus as mentioned above.
