Title
(EN) Coiled Tubing Extended Reach with Downhole Motors
(FR) PORTÉE ÉTENDUE DE TUBAGE HÉLICOÏDAL À MOTEURS DE FOND DE TROU
Abstract
(EN) Disclosed is a method to enhance the reach of coiled tubing in the lateral section of a wellbore. The application of this method may enhance the use of coiled tubing in drilling very deep flowing wells. Similarly, the method may be applied in increasing the reach of the tubing for other coiled tubing well intervention applications. The method involves the use of downhole motor assemblies, stabilizers, and dynamic torque arrestors to rotate coiled-tubing string.
(FR) L'invention concerne un procédé pour améliorer la portée d'un tubage hélicoïdal dans la section latérale d'un puits de forage. L'application de ce procédé permet d'améliorer l'utilisation du tubage hélicoïdal pour le forage de puits éruptifs très profonds. De même, le procédé peut s'appliquer pour augmenter la portée du tubage en vue d'autres applications d'intervention sur puits à tubage hélicoïdal. Le procédé implique l'utilisation d'ensembles moteurs de fond de trou, de stabilisateurs et de dispositifs d'arrêt de couple dynamiques pour faire tourner une colonne à tubage hélicoïdal.
