Title (EN) SYSTEMS AND METHODS FOR PROVIDING ELECTRICAL TRANSMISSION IN DOWNHOLE TOOLS
(FR) SYSTÈMES ET PROCÉDÉS POUR FOURNIR UNE TRANSMISSION ÉLECTRIQUE DANS DES OUTILS DE FOND
Abstract:
(EN) A downhole drilling tool (100) includes a housing (102) defining an axial passageway (104) and a shaft (106) mounted for rotation within the axial passageway such that the housing and shaft form an annular gap. An electrical connector provides a signal to the shaft. The electrical connector includes a first lead assembly (112) coupled to the housing and the shaft, and a second lead assembly coupled to the housing and the shaft. Each lead assembly has an outer ring electrode (114) fixed to the housing and an inner ring electrode (116) fixed to the shaft for rotation therewith such that connector gaps are formed between the outer ring electrodes and the inner ring electrodes. Drilling fluid (110) is pumped through the annular gap (108) to flow through the connector gaps (118a, 118b, 118c) to complete electrical connections between the outer ring electrodes and inner ring electrodes.
(FR) L'invention concerne un outil de forage de fond (100) comprenant un boîtier (102) définissant un passage axial (104) et un arbre (106) qui est monté pour effectuer un mouvement de rotation dans ce passage axial de manière que le boîtier et l'arbre forment une ouverture annulaire. Un connecteur électrique fournit un signal à l'arbre. Le connecteur électrique comprend un premier ensemble fil (112) qui est couplé avec le boîtier et l'arbre, et un deuxième ensemble fil qui est couplé au boîtier et à l'arbre. Chaque ensemble fil comporte une électrode annulaire externe (114) qui est fixée sur le boîtier ainsi qu'une électrode annulaire interne (116) qui est fixée sur l'arbre pour y effectuer un mouvement de rotation, de sorte que des interstices de connexion se forment entre les électrodes annulaires externes et les électrodes annulaires internes. Un fluide de forage (110) est pompé à travers l'ouverture annulaire (108) de manière à s'écouler à travers les interstices de connexion (118a, 118b, 118c) pour compléter les connexions électriques entre les électrodes annulaires externes et les électrodes annulaires internes.
