Abstract
Un outil de télémétrie comprenant un ensemble pulseur, un joint primaire, un générateur dimpulsions de pression de fluide et un joint secondaire. Lensemble pulseur comprend un boîtier et un arbre dentraînement sétendant hors dune ouverture du boîtier. Le joint primaire entoure et se scelle contre larbre de transmission pour sceller louverture dans le logement. Le générateur dimpulsions de pression de fluide comprend un stator traversé par un alésage configuré pour se fixer de manière fixe au logement ou à un collier de forage entourant le générateur dimpulsions de pression de fluide, et un rotor fixé de manière fixe à larbre dentraînement. Larbre dentraînement et le rotor tournent par rapport au stator fixe pour générer des impulsions de pression dans la boue sécoulant dans le générateur dimpulsions de pression de fluide. Le joint secondaire est logé dans lalésage du stator et entoure et isole une partie de larbre de transmission sortie du logement ou une partie du rotor afin de réduire la quantité de boue, de gravillons et de débris sur le joint primaire qui pourraient sinon provoquer une usure ou endommager le joint primaire.
