Wellhead tiedown system
A system includes a wellhead tiedown system having a lock screw configured to move axially within an aperture of a spool. The wellhead tiedown system also has a first gland configured to couple to the spool within the aperture and block axial movement of the lock screw in a first direction, and a second gland configured to couple to the lock screw and block axial movement of the lock screw without rotation.
1. A system, comprising:
a wellhead tiedown system, comprising:
a lock screw configured to move axially within an aperture of a spool; and
a first gland configured to threadably couple to the spool within the aperture and to block axial movement of the lock screw in one direction along an axial axis by engaging a flange of the lock screw while the first gland is threadably coupled to the spool;
wherein the flange comprises a flange contact face and the first gland comprises a gland contact face, and the flange and gland contact faces enable rotation of the lock screw to drive rotation of the first gland via engagement between the respective contact faces of the lock screw and the first gland to uncouple the first gland from the spool, thereby facilitating removal of the lock screw and the first gland from the aperture of the spool.
2. The system of claim 1 , wherein the flange comprises a groove configured to receive an o-ring.
3. The system of claim 1 , wherein the lock screw comprises a tip with a groove, and wherein the groove is configured to receive an o-ring.
4. The system of claim 1 , comprising a gland tool configured to threadably couple the first gland to the spool, wherein the first gland comprises slots and protrusions that engage corresponding protrusions and slots on the gland tool.
5. The system of claim 4 , wherein the gland tool comprises a cavity that enables the gland tool to move axially over the lock screw when threadably coupling the first gland to the spool.
6. The system of claim 1 , comprising a hydrocarbon extraction system, wherein the wellhead tiedown system is configured to secure a hanger within the hydrocarbon extraction system.
7. The system of claim 1 , comprising a second gland configured to couple to the lock screw and to block axial movement of the lock screw without rotation.
8. A system, comprising:
a hydrocarbon extraction system, comprising:
a spool;
a hanger suspended within the spool; and
a wellhead tiedown system configured to secure the hanger within the spool, the wellhead tiedown system, comprising:
a lock screw configured to move axially within an aperture of the spool;
a first gland configured to couple to the spool within the aperture and to block axial movement of the lock screw in one direction along an axial axis of the lock screw; and
a second gland configured to threadably couple to the lock screw and to threadably couple to the spool, thereby blocking axial movement of the lock screw without rotation;
wherein the first gland is configured to block the axial movement of the lock screw in the one direction along the axial axis of the lock screw by engaging a flange of the lock screw, the flange comprises a flange contact face and the first gland comprises a gland contact face, and the flange and gland contact faces enable the lock screw to rotate the first gland.
9. The system of claim 8 , wherein the flange comprises a groove configured to receive an o-ring.
10. The system of claim 8 , comprising a gland tool configured to couple the first gland to the spool, wherein the first gland comprises slots and protrusions that are configured to engage corresponding protrusions and slots on the gland tool.
11. The system of claim 8 , comprising packer seals positioned between the first gland and the second gland along the axial axis.
12. The system of claim 8 , wherein the lock screw comprises a tip configured to engage a component within the spool, wherein the first gland is configured to be positioned between the tip of the lock screw and the second gland along the axial axis.
