Abstract

Un outil de forage directionnel comprend un logement définissant une cavité centrale pour permettre la transmission de fluide de forage au train de forage. Un moteur contenu dans le logement comprend un ensemble rotor-stator et produit un mouvement excentré du rotor. Un inverseur ou un ensemble dabsorption des chocs placé le long du logement en amont du moteur fonctionne pour dilater et comprimer la cavité centrale en réponse à des changements de pression de fluide produits par la circulation du fluide de forage. Un assemblage de robinet comportant une tête de débit multivoie qui tourne par laction du moteur et un limiteur de débit multivoie crée une configuration variable de pics de pression dans le fluide de forage lorsque les voies de la tête de débit salignent et se désalignent sur les voies du limiteur de débit, qui à son tour entraîne un effet de percussion et un mouvement axial dans le train de forage.
