Title:
MULTI-STRING COMPOSITE COILED TUBING SYSTEM
Document Type and Number:
WIPO Patent Application WO2001059250
Kind Code:
A9
Abstract:
A reel assembly (100) having three reels (104) disposed side-by-side on a shaft (102) pays out coiled tubing (38) to an injector (36). A conveyor (108) is used to support and guide the coiled tubing (38) during travel from the reels (104) to the injector (36). The conveyor (108) is selectively rotatable such that the conveyor may be directed to the reel (104) which actively pays out the coiled tubing (38). In another embodiment, two reels (104) are slidably disposed side-by-side on a shaft (102). A conveyor (108) is used to support and guide the coiled tubing (38) during travel from the reels to the injector (36). In this embodiment, the conveyor (108) is directed to a specific location on the shaft (102) and the reels (104) slid into the specific location for coiled tubing payout.
