Abstract
A coiled tubing unit includes a coiled tubing assembly and a slickline assembly sharing an axis of rotation with the coiled tubing assembly. A shaft of the coiled tubing assembly is received by bearings on a slickline drum of the slickline assembly and extends through an interior of the slickline drum. A swivel joint connection is rotatably affixed on an end of the shaft as it exits the interior of the slickline drum, thus allowing for introduction of fluid or cabling into the shaft and into the coiled tubing. The coiled tubing drum and slickline drum can rotate independently and are powered independently of each other. The coiled tubing and slickline assemblies are preferably affixed to a removable module, the removable module being positioned on a skid having a power unit and appropriate controls.
Claims20
An apparatus comprising:
- a skid having a power unit positioned thereon, said power unit having an engine, a first hydraulic pump and a second hydraulic pump;
- and
- a module removably positioned on said skid, said module having a primary reel assembly with a first motor and a secondary reel assembly with a second motor, said primary reel assembly and said secondary reel assembly having a common axis of rotation and being independently rotatable, said first motor being connected to said first hydraulic pump via a first hydraulic hose, said second motor being connected to said second hydraulic pump via a second hydraulic hose.
A coiled tubing unit comprising:
- a base;
- a coiled tubing assembly affixed to said base, said coiled tubing assembly having a coiled tubing drum with opposing flanges and a shaft, said shaft extending through an interior of said coiled tubing drum and having a hole drilled therein in a position between said opposing flanges of said coiled tubing drum;
- a secondary drum positioned adjacent said coiled tubing assembly such that said secondary drum and said coiled tubing drum share an axis of rotation, said secondary drum having at least one bearing unit, said shaft of said coiled tubing assembly being received by said at least one bearing unit and extending through an interior of said secondary drum;
- and
- a swivel connection affixed to an end of said shaft adjacent said secondary drum, said swivel connection rotatable relative to said shaft, said swivel connection adapted to allow for introduction of a fluid or a cable into a hollow interior of said shaft.
An apparatus comprising:
- a base;
- a coiled tubing assembly affixed to said base, said coiled tubing assembly having a coiled tubing drum and a shaft;
- and
- a secondary assembly affixed to said base, said secondary assembly having a secondary drum and at least one bearing unit, said shaft of said coiled tubing assembly being received by said at least one bearing unit so as to pass through an interior of said secondary drum such that said coiled tubing drum is rotatable independently of said secondary drum.
