Abstract
The present invention, in certain embodiments, discloses a method for controlling an arch portion of coiled tubing above an injector for injecting the coiled tubing into a bore, the method including monitoring at least height of the coiled tubing arch with monitor apparatus that produces a signal indicative of the height, sending said signal to arch maintenance apparatus, and maintaining height of the arch portion with the arch maintenance apparatus using said signal indicative of said height.
Claims17
A method for controlling an arch portion of coiled tubing above an injector for injecting the coiled tubing into a bore, the method comprising
- monitoring height of the arch portion of the coiled tubing with monitor apparatus that produces a signal indicative of said height,
- sending said signal to arch maintenance apparatus,
- maintaining position of the arch portion with the arch maintenance apparatus using said signal indicative of said height,
- wherein the monitor apparatus includes a supported roller mechanism movable by the arch portion and positioned about the arch portion, the roller mechanism on a structural member that itself moves with respect to a support member having a plurality of actuatable electronic devices spaced-apart, a portion of the structural member activating a particular one of the plurality of actuatable electronic devices adjacent thereto, a signal sendable from said particular actuatable electronic device indicative of height of said device which is corresponds to a height of the arch portion, said method further comprising
- controlling height of the arch portion with said arch maintenance apparatus based on the signal from the particular actuatable electronic device.
A method for controlling an arch portion of coiled tubing above an injector for injecting the coiled tubing into a bore, the method comprising
- monitoring height of the arch portion of the coiled tubing with monitor apparatus that produces a signal indicative of said height,
- sending said signal to arch maintenance apparatus,
- maintaining position of the arch portion with the arch maintenance apparatus using said signal indicative of said height,
- wherein the arch maintenance apparatus includes a control system for controlling the injector, the method further comprising
- controlling the injector with the arch maintenance apparatus to control arch portion position.
A method for controlling an arch portion of coiled tubing above an injector for injecting the coiled tubing into a bore, the method comprising
- monitoring height of the arch portion of the coiled tubing with monitor apparatus that produces a signal indicative of said height,
- sending said signal to arch maintenance apparatus, and
- maintaining position of the arch portion with the arch maintenance apparatus using said signal indicative of said height,
- wherein the monitor apparatus includes a follower member positioned adjacent and movable by the arch portion, the follower member on a structural member that itself moves with respect to a support member having a plurality of spaced-apart actuatable electronic devices, a portion of the structural member activating a particular actuatable electronic device of the plurality thereof adjacent thereto, a signal sendable from said particular actuatable device indicative of follower position to the arch maintenance apparatus, said follower position corresponding to a height of the arch portion, said method further comprising
- controlling height of the arch portion with said arch maintenance apparatus based on the signal from the particular actuatable electronic device.
An arch control system for controlling an arch portion of coiled tubing above an injector for injecting coiled tubing into a bore, the arch control system comprising
- monitor apparatus for monitoring height of the arch portion of the coiled tubing to produce a signal indicative of said height and transmitting said signal to arch maintenance apparatus,
- arch maintenance apparatus for maintaining position of said arch portion using said signal from said monitor apparatus, and
- a follower member positioned adjacent and movable by the arch portion, the follower member on a structural member that itself moves with respect to a support member having a plurality of spaced-apart actuatable electronic devices, a portion of the structural member activating a particular actuatable electronic device of the plurality thereof adjacent thereto, a signal sendable from said particular actuatable electronic device indicative of follower position to the arch maintenance apparatus, said follower position corresponding to a height of the arch portion.
