REAL TIME TRACKING OF BENDING FORCES AND FATIGUE IN A TUBING GUIDE

A coiled tubing deployment system includes an offshore rig having a reel positioned thereon and coiled tubing wound on the reel. A tubing guide is operatively coupled to receive the coiled tubing and to direct the coiled tubing into the water, with a weight sensor positioned to measure the weight of...

Beschreibung
Zusammenfassung:	A coiled tubing deployment system includes an offshore rig having a reel positioned thereon and coiled tubing wound on the reel. A tubing guide is operatively coupled to receive the coiled tubing and to direct the coiled tubing into the water, with a weight sensor positioned to measure the weight of the portion of coiled tubing deployed into the water. A first set of bend sensors are positioned at a first location on the tubing guide to measure a real-time strain assumed by the tubing guide at the first location. A data acquisition system is communicably coupled to the weight sensor and the first set of bend sensors, and receives and processes weight measurement signals and bend sensor signals in order to provide an output signal indicative of a real-time bending fatigue of the tubing guide.
