Title (EN) METHODS AND SYSTEMS FOR REDUCING DRAG AND FRICTION DURING DRILLING
(FR) PROCÉDÉS ET SYSTÈMES DE RÉDUCTION DE TRAINÉE ET DE FROTTEMENT PENDANT LE FORAGE
Abstract:
(EN) Embodiments disclosed herein describe a rotating flow coupler that is configured to couple multiple sections of a casing for a horizontal well, wherein the rotating flow coupler is configured to rotate relative to the casing allowing an additional degree of freedom for equipment being lowered into the well. This may allow for equipment such as coil tubing, drilling string, casings strings, etc. to reach a total distance of deeper laterals.
(FR) Des modes de réalisation de la présente invention décrivent un connecteur d'écoulement rotatif qui est conçu pour accoupler de multiples sections d'un tubage pour un puits horizontal, le connecteur d'écoulement rotatif étant conçu pour tourner par rapport au tubage, ce qui permet un degré de liberté supplémentaire pour l'équipement qui est abaissé dans le puits. Ceci peut permettre qu'un équipement tel qu'un tube enroulé, un train de tiges de forage, des chaînes de tubage, etc. atteigne une distance totale de déviations latérales plus profondes.
