Abstract
Ensemble de tiges de forage comprenant deux tiges de forage électriquement conductrices. Chaque tige de forage comprend un filetage femelle et mâle. La partie femelle et la partie mâle sont filetées ensemble pour former une connexion. Une étoffe tissée électriquement isolante recouvre en l'épousant le filetage de la broche de connexion. Une rondelle annulaire électriquement isolante sépare les faces du joint d'étanchéité de la connexion. L'ensemble fonctionne de sorte à créer une discontinuité électrique lorsqu'installé dans un train de tiges conducteur.
