Produksjonsrøroppheng for å henge opp en produksjonsrørstreng fra et brønnhodehus

Wellhead assembly comprising a tubing hanger body (152) including a production bore (44) in fluid communication with the tubing bore, and a fluidly isolated annulus bore (50) in fluid communication with the tubing annulus, a valve open inlet port, and a valve closed inlet port, each inlet port located at least partially within the tubing hanger body (152), a valve (162) external of the tubing hanger body for controlling fluid flow in the production bore, a hydraulically actuated ball valve (52) within the annulus bore (50) of the tubing hanger body and including a ball rotatable between opened and closed positions about an axis substantially stationary with respect to the tubing hanger body and selectively moveable to open and close the annulus bore, an actuator sleeve (54) generally surrounding and radially outward of an outer surface of the ball and connected to the ball, the actuator sleeve (54) being moveable in response to fluid pressure in the valve open inlet port to move the ball to the open position, and moveable in response to fluid pressure in the valve closed inlet port to move the ball to the closed position; and an upper seat sleeve (56) and a lower seat sleeve (57) each substantially stationary axially with respect to the tubing hanger body, and the upper seat sleeve (56) having a sealing diameter with the tubing hanger body greater than the sealing diameter between the upper seat sleeve (56) and the ball, and a seal for sealing between the tubing hanger body and the actuator sleeve to fluidly isolate the valve open inlet port from the valve closed inlet port.
