Patent

CA 2455396

There is disclosed an electrically insulating device in the form of a sleeve (12) for a downhole tool, for electrically insulating a first threaded electrically conductive member in the form of an anchor sub (16) from a second threaded electrically conductive member in the form of an insulated sub (18). An assembly (10) including the sleeve (12) has particular use in measurement while drilling (MWD)/logging while drilling (LWD) procedures. In one embodiment, a third member in the form of a threaded electrically conductive sleeve sub (20) is coupled to the insulated sub by a second sleeve (14), to create an insulated gap between the anchor and sleeve subs (16, 20).

L'invention porte sur un dispositif d'isolation électrique sous forme de manchon (12) pour un outil de perforation vers le bas, permettant d'isoler un premier élément électriquement conducteur fileté sous forme de potentiomètre intermédiaire d'ancrage (16) d'un second élément électriquement conducteur fileté sous forme d'un potentiomètre intermédiaire isolé (18). On prévoit un ensemble (10) comportant le manchon (12) spécialement conçu pour mesurer lors d'opérations de perforation (MWD)-diagraphie et de perforation (LWD). Selon un mode de réalisation, un troisième élément sous forme de potentiomètre intermédiaire à manchon électriquement conducteur isolé (20) est couplé à un potentiomètre intermédiaire isolé par l'intermédiaire d'un second manchon (14) afin de créer un espace isolé entre les potentiomètres intermédiaires d'ancrage et de manchon (16, 20).
