Method of reducing pipe fatigue by eliminating short movements |
摘要 |
This invention relates to a method for use in coiled tubing operations wherein fatigue of the coiled tubing owing to short trips is reduced by reducing the number of bending and straightening events that coiled tubing undergoes to accomplish a particular wellbore objective. The invention relates to a method that allows the coiled tubing reel and tubing reeled thereon to remain stationary while making small movements of coiled tubing using the injector. The invention also relates to a method that permits synchronized movement of coiled tubing between the coiled tubing reel and injector.
