tubing head

The tubing head is installed on top of the casing head, and its function is to suspend the tubing inside the well and seal the annular space between the tubing and the reservoir casing. At present, the hanging method of top screw valve is commonly used, which means installing a top screw valve on the four-way of the casing, and the top screw valve has a conical channel with a large upper part and a small lower part inside. The oil pipe hanger is also a conical problem, with a sealing ring on it. Under the tension of the entire wellbore oil pipe weight, the oil pipe hanger firmly sits in the seat of the top screw valve. The function of the top wire is to prevent the oil pipe column from being pushed out during high internal pressure.

The oil pipe head and oil pipe tee are used to suspend oil pipes and seal the annular space of oil pipes. Their characteristics include:

1. The secondary sealing forms between the oil pipe hanger and the reducing flange include O-ring sealing, grease injection BT sealing, and metal to metal sealing;

2. The sealing forms of oil pipe hanger and oil pipe head include metal metal seal, special synthetic rubber seal, or metal seal+special synthetic rubber seal;

3. Equipped with grease injection valve port and sealing test port;

4. The sealing forms of the lower part of the oil pipe head include O-ring sealing, grease injection BT sealing, and metal sealing;

5. The oil pipe hanger and oil pipe head reducing flange can be used for direct cable crossing, and can be equipped with downhole safety valves to control pipeline interfaces;

6. The side outlet link is threaded or threaded flange type, and is equipped with VR threads for easy valve replacement operations.
