Abstract
A wellhead assembly includes a wellhead housing; a tubing hanger, plug, back pressure valve, two-way check valve, BOP test plug, temporary abandonment plug, or other device; and a torque ring. The wellhead housing includes an inner bore. The wellhead housing has one or more mating grooves formed on an inner wall of the wellhead housing. The tubing hanger, plug, back pressure valve, two-way check valve, BOP test plug, temporary abandonment plug, or other device is positioned within the inner bore of the wellhead housing. The torque ring is positioned within a slot formed in the tubing hanger or other device. The torque ring includes a protrusion extending beyond the tubing hanger and into the mating groove.
Claims17
A wellhead assembly comprising:
- a wellhead housing, the wellhead housing including an inner bore, the wellhead housing having one or more mating grooves formed on an inner wall of the wellhead housing;
- a tubing hanger, the tubing hanger positioned within the inner bore of the wellhead housing;
- and
- a torque ring, the torque ring positioned within a slot formed in the tubing hanger, the torque ring including a protrusion, the protrusion extending beyond the tubing hanger and into the mating groove;
- wherein the torque ring includes a torque transfer feature and the slot of the tubing hanger includes a corresponding torque transfer feature.
A wellhead assembly comprising:
- a wellhead housing, the wellhead housing including an inner bore, the wellhead housing having one or more mating grooves formed on an inner wall of the wellhead housing;
- an alignment shoulder, the alignment shoulder positioned within the inner bore of the wellhead housing;
- and
- a torque ring, the torque ring positioned within a slot formed in the alignment shoulder, the torque ring including a protrusion, the protrusion extending beyond the alignment shoulder and into the mating groove;
- wherein the torque ring includes a torque transfer feature and the slot of the alignment shoulder includes a corresponding torque transfer feature.
A method comprising:
- providing a wellhead housing, the wellhead housing including an inner bore, the wellhead housing having one or more mating grooves formed on an inner wall of the wellhead housing;
- positioning a torque ring into a slot formed in a tubing hanger, the torque ring including a protrusion, the protrusion extending beyond the tubing hanger, the torque ring including a torque transfer feature and the slot of the tubing hanger including a corresponding torque transfer feature;
- inserting the tubing hanger into the inner bore of the wellhead housing;
- engaging the wellhead housing with the protrusion;
- deflecting the torque ring inward until the protrusion is within a diameter of the inner bore of the wellhead housing;
- aligning the protrusion with the mating groove;
- biasing the protrusion radially outward into the mating groove;
- and
- preventing rotation of the tubing hanger.
