Lubricator for use with coiled tubing apparatus and universal rig having coiled tubing and top drive capability
View Patent ↗A lubricator for use with a coiled tubing injector comprising an elongated housing having a first end and a second end. There is a guide system disposed in the housing for guiding coiled tubing passing through the housing, a first director proximal the first end of the housing to direct the coiled tubing in a first direction and a second director proximal the second end of the housing to direct the coiled tubing in a second direction.
1. A lubricator for use with a coil tubing injector comprising:
an elongated, sealing housing having a first end and a second end;
a guide system disposed in said housing for guiding coil tubing passing through said housing;
a first director proximal said first end of said housing to direct said coil tubing in a first direction; and
a second director proximal said second end of said housing to direct said coil tubing in a second direction, wherein said second direction is different from and at an angle to said first direction.
2. The lubricator of claim 1 , wherein there is at least one intermediate director between said first and second directors to direct said coil tubing toward said second direction.
3. The lubricator of claim 1 , wherein said first end of said housing has a first axis and said second end of said housing has a second axis, said first and second axes being at an angle to one another.
4. The lubricator of claim 1 , wherein said housing is arced.
5. The lubricator of any one of claim 3 or 4 , wherein said guide system comprises a first set of longitudinally spaced inner guide rollers and a second set of longitudinally spaced outer guide rollers, at least some of respective ones of said inner guide rollers and said outer guide rollers being clustered along the length of said housing.
6. The lubricator of claim 5 , wherein said guide system comprises a plurality of longitudinally spaced, inner rollers and a plurality of longitudinally spaced outer guide blocks, at least some of respective ones of said inner rollers and said outer guide blocks being clustered along the length of said housing.
7. The lubricator of claim 5 , wherein said guide system comprises a plurality of longitudinally spaced inner guide blocks and a plurality of longitudinally spaced outer guide blocks, at least some of respective ones of said inner and outer guide blocks being clustered along the length of said housing.
8. The lubricator of claim 1 , wherein said elongated housing is rectangular in cross-section.
9. The lubricator of claim 1 , wherein said housing is connected at its first end to a universal joint.
10. The lubricator of claim 9 , wherein said housing comprises a first end and a second end and first and second, spaced side walls, said first director comprising a first inner guide and a first outer guide, said first inner and outer guides being clustered proximal said first end of said housing and said second director comprises a second inner guide and a second outer guide, said second inner and outer guides being clustered proximal said second end of said housing, said first inner guide being close to said first side wall, said first outer guide being closer to said second side wall, said second inner guide being further from said first side wall than said first inner guide, said second outer guide being close to said second side wall than said first outer guide.
11. The lubricator of claim 10 , wherein said inner and outer guides comprise rollers.
12. The lubricator of claim 10 , wherein said inner guides comprise rollers and said outer guides comprise guide blocks.
13. The lubricator of claim 10 , wherein said inner and outer guides comprise guide blocks.
14. The lubricator of claim 13 wherein the mast is pivotable relative to the support.
15. The lubricator of claim 1 , wherein said housing is substantially straight.
16. The lubricator of claim 15 , wherein said guide system comprises a first set of longitudinally spaced inner rollers and a second set of longitudinally spaced outer rollers at least some of respective ones of said inner and outer rollers being clustered along the length of said housing.
17. A rig for selectively inserting coil tubing or threaded tubulars into a wellbore comprising:
a support;
a mast extending upward from said support;
a top drive carried by said mast for longitudinal movement therealong, said top drive having a first axis extending therethrough;
a CT injector carried by said mast, said injector having a second axis offset from said first axis and
the lubricator of claim 1 , attached to said CT injector.
18. The rig of claim 17 wherein the injector is rigidly secured to the mast by a support bracket.
19. The lubricator of claim 17 wherein the CT injector is removably secured to the mast.
