Abstract
A tubewire buckling mitigation assembly for use with injection of tubewire into coiled tubing. The mitigation assembly includes a passageway having a small diameter passage, an intermediate diameter section and first and second tapered transition sections.
Claims13
A tubewire injection system for injecting tubewire into coiled tubing, the system comprising:
- a tubewire injector having a drive mechanism to apply an axial pushing force to inject the tubewire;
- coiled tubing having an inner diameter and presenting an open whip end into which the tubewire is injected;
- and
- a tubewire buckling mitigation assembly located between the injector and the coiled tubing and comprising a passageway which receives the tubewire from the injector, the passageway providing:
- a small diameter passage having an interior diameter that inhibits buckling of the tubewire;
- an intermediate diameter section having an interior diameter that permits limited buckling of the tubewire;
- and
- a first tapered transition section disposed between the small diameter passage and the intermediate diameter section;
- and
- a second tapered transition section disposed between the intermediate diameter section and the open whip end, the second tapered transition section providing a tapered transition which opens from the intermediate diameter section to the open whip end.
