Universal rig with vertical stand for tubulars
View Patent ↗The rig ( 10 ) is provided for electively inserting either coiled tubing or a threaded tubular through a rig floor and into a well. The rig includes a coiled tubing injector ( 16 ) supported on a mast ( 14 ) when in an operative position to insert coiled tubing into the well, and a top drive ( 18 ) movable along an axis of the mast when in an operative position to insert the threaded tubular into the well. The rack or support ( 20 ) is secured to the mast for receiving a plurality of substantially vertical threaded tubular joints therein when the mast is in an operative position. Tubular joints may be moved between the top drive and the tubular support when running threaded tubulars into or out of the well.
1. A rig for selectively inserting coiled tubing or threaded tubulars through a rig floor and into a well, the rig comprising:
a mast extending upward from a rig base when in an operative position;
a coiled tubing reel for paving out and taking in coiled tubing:
a coiled tubing injector supported on the mast when in an operative position and receiving the coiled tubing from one side of the mast to insert the coiled tubing into the well;
a top drive movable along an axis of the mast when in an operative position and receiving coiled tubing from the one side of the mast to insert the threaded tubulars into the well; and
a support secured to the mast for receiving a plurality of substantially vertical threaded tubular joints therein from an opposing side of the mast when the mast is in the operative position, such that the support is opposite the coiled tubing reel with respect to the mast and tubular joints may be moved between the top drive and the tubular support when running threaded tubulars into or out of the well.
2. The rig as defined in claim 1 , wherein the support supports a plurality of threadedly connected and vertically spaced tubular joints within the tubular support.
3. The rig as defined in claim 1 , wherein the support supports one or more drill collars therein when the mast is in the operative position, such that the one or more drill collars may be moved between the coiled tubing and the support when running coiled tubing into and out of the well.
4. The rig as defined in claim 1 , wherein the support supports tubular joints on each side of the mast.
5. The rig as defined in claim 1 , wherein the support is connected to a pivotable mast, such that the support may be placed in a travel position when the mast is lowered for transport.
6. The rig as defined in claim 1 , wherein the threaded tubular joints within the support include drill pipe for insertion into the well to drill at least a portion of the well.
7. The rig as defined in claim 1 , wherein the coiled tubing injector is laterally movable relative to the mast between an inoperative position to an operative position.
8. The rig as defined in claim 1 , wherein the coiled tubing injector is supported on the mast above the top drive, such that coiled tubing passes through the top drive and then through the rig floor and into the well.
9. The rig as defined in claim 1 , wherein the coiled tubing injector when in the operative position is spaced from a centerline of the mast, and a lubricator extends downward from the injector and directs the coiled tubing through the rig floor and into the well.
10. The rig as defined in claim 1 , wherein the mast is laterally movable with respect to the rig base from a position wherein the top drive is aligned with an axis of a well to a position wherein the injector is aligned with the axis of the well.
11. The rig as defined in claim 1 , wherein the mast pivots relative to the rig base from an inoperative position wherein a centerline of the injector is out of alignment with the well and an operative position wherein a centerline of the injector is aligned with the well.
12. The rig as defined in claim 1 , wherein the coiled tubing injector is supported on a trailer structurally separate from the rig base.
13. A rig for selectively inserting coiled tubing or threaded tubulars through a rig floor and into a well, the rig comprising:
a mast extending upward from a rig base when in an operative position;
a coiled tubing reel for paving out and taking in coiled tubing;
a coiled tubing injector supported on the mast when in an operative position and receiving the coiled tubing from one side of the mast to insert the coiled tubing into the well;
a top drive movable along an axis of the mast when in an operative position and receiving coiled tubing from the one side of the mast to insert the threaded tubulars into the well;
a support secured to the mast for receiving a plurality of substantially vertical threaded tubular joints therein from an opposing side of the mast when the mast is in the operative position, such that the support is opposite the coiled tubing reel with respect to the mast and tubular joints may be moved between the top drive and the support when running threaded tubulars into or out of the well; and
the support supports a plurality of threadedly connected and vertically spaced tubular joints within the support.
14. The rig as defined in claim 13 , wherein the support supports one or more drill collars therein when the mast is in the operative position, such that the one or more drill collars may be moved between the coiled tubing and the support when running coiled tubing into and out of the well.
15. The rig as defined in claim 13 , wherein the support supports tubular joints on each side of the mast.
16. The rig as defined in claim 13 , wherein the support is pivotally connected to the mast, such that the support may be placed in a travel position when the mast is lowered for transport.
17. The rig as defined in claim 13 , wherein the coiled tubing injector is supported on a trailer structurally separate from the rig base.
18. A method of selectively inserting coiled tubing or threaded tubulars through a rig floor and into a well utilizing a mast extending upward from a rig base when in an operative position, a coiled tubing injector supported on the mast when in an operative position, and a top drive movable along an axis of the mast when in an operative position to insert threaded tubulars into the well, the method comprising:
supplying coiled tubing to the injector from a coiled tubing reel positioned on one side of the mast;
securing a support to the mast for receiving a plurality of substantially vertical threaded tubular joints therein to an opposing side of the mast when the mast is in the operative position;
selectively passing coiled tubing through the coiled tubing injector and into the well; and
selectively moving the tubular joints between the top drive and the support when running threaded tubulars into or out of the well.
19. The method as defined in claim 18 , further comprising:
supporting a plurality of threadedly connected and vertically spaced tubular joints within the support.
20. The method as defined in claim 18 , further comprising:
supporting one or more drill collars within the support when the mast is in the operative position; and
moving the one or more drill collars between the coiled tubing and the support when running coiled tubing into and out of the well.
21. The method as defined in claim 18 , further comprising:
supporting drill pipe within the support;
drilling at least a portion of the well utilizing the drill pipe in the well; and
tripping the drill pipe out of the well and into the support.
