Abstract
(EN) A removable real time clock battery ("RRTCB") assembly is disclosed herein. The RRTCB assembly has an outer housing removably mounted in a port of a downhole tool. The outer housing is adapted to receive at least a portion of an inner housing. The inner housing has a cavity therein and is mounted in the port of the downhole tool. The inner housing is removably disposed within the outer housing. A real time clock battery is removably disposed in the cavity of the inner housing. The real time clock battery electrically connects to a clock disposed within the downhole tool. The RRTCB assembly can be readily removed from the downhole tool or bottomhole assembly (while at the earth's surface) without otherwise disassembling the downhole tool. The real time clock battery can then be removed and replaced or installed if not present.
(FR) Un bloc-batterie d'horloge à temps réel amovible (« RRTCB »). L'ensemble RRTCB a un boîtier externe monté de manière amovible dans un orifice d'un outil de fond de trou. Le boîtier externe est conçu pour recevoir au moins une partie d'un boîtier interne. Le boîtier interne comporte une cavité et est monté dans l'orifice de l'outil de fond de trou. Le boîtier interne peut être disposé de manière amovible dans le boîtier externe. Une batterie d'horloge à temps réel est disposée de manière amovible dans la cavité du boîtier interne. La batterie d'horloge à temps réel se connecte électriquement à une horloge disposée à l'intérieur de l'outil de fond de trou. L'ensemble RRTCB peut être facilement retiré de l'outil de fond de trou ou de l'ensemble fond de trou (lorsqu'il se trouve au niveau de la surface de la terre) sans démonter l'outil de fond de trou. La batterie d'horloge à temps réel peut ensuite être retirée et remplacée ou installée si elle n'est pas présente.
