Title

(EN) MULTI-STRING COMPOSITE COILED TUBING SYSTEM

(FR) SYSTEME DE TUBAGE ENROULE COMPOSE A RAMES MULTIPLES

Abstract

(EN) 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.

(FR) La présente invention concerne un ensemble de bobinage (100) comprenant trois bobines (104) disposées les unes à côté des autres sur un arbre (102), servant à dévider du tubage enroulé (38) jusqu'à un injecteur (36). Un élément transporteur (108) sert à supporter et à guider le tubage enroulé (38) durant son déplacement des bobines (104) à l'injecteur (36). L'élément transporteur (108) peut tourner de manière sélective de sorte qu'il peut être dirigé vers la bobine (104) qui déroule le tubage enroulé (38) de manière active. Dans un autre mode de réalisation, deux bobines (104) sont disposées côte à côte sur l'arbre (102) de manière à pouvoir coulisser. Un élément transporteur (108) sert à supporter et à guider le tubage enroulé (38) durant son déplacement des bobines (104) à l'injecteur (36). Dans ce mode de réalisation, l'élément transporteur (108) est dirigé vers un endroit spécifique de l'arbre (102) et les bobines (104) coulissent pour se placer à cet endroit spécifique afin de dérouler le tubage.
