摘要： An adjustable hanger system secures a hanger to a wellhead such that a downward extending tubular may be tensioned at a selected level. The wellhead includes a housing having a plurality of axially spaced grooves, with selected grooves receiving a support member therein. The wellhead housing also has an axially elongate and generally cylindrical sealing surface spaced above the plurality of grooves for sealing engagement with a seal element. The hanger is axially movable relative to the plurality of grooves. The hanger is supported by the support member which is radially movable into selected ones of a plurality of grooves. A lockdown member may also move into selected ones of the plurality of grooves for preventing axially upward movement of the hanger relative to the wellhead.

摘要： A hanger assembly includes: a main body; a lock ring coupled to the main body and configured to expand radially outward into a profile on an inner diameter of the wellhead; and an actuator, wherein the actuator is capable of transferring an axial force from the actuator into outward radial expansion of the lock ring toward the profile on the inner diameter of the wellhead. An interface between the actuator and the lock ring is shaped such that: axially downward movement of the actuator from a starting position to an intermediate position actuates the lock ring into the profile; and axially downward movement of the actuator from the intermediate position to a pre-load position applies a pre-load to the hanger assembly.

摘要： A space-out mechanism that may be used in a tubing hanger system to install a tubing hanger and rigidize the tubing hanger and a casing hanger within a wellhead housing in a single trip is provided. The space-out mechanism may include two pieces that are configured to rotate against each other such that the axial length of the space-out mechanism can be adjusted to remove any axial gaps created in the installation of the tubing hanger or rigidizing of the tubing hanger and casing hanger within the wellhead housing. The two pieces of the space-out mechanism may include a ramp ring and a piston. The ramp ring and piston may each have ramp surfaces that rotate and bear against each other until the system is rigidized.
