Title
(EN) USING A DOWNHOLE ACCELEROMETER TO MONITOR VIBRATION
(FR) UTILISATION D'UN ACCÉLÉROMÈTRE EN PROFONDEUR DE FORAGE POUR SURVEILLER UNE VIBRATION
Abstract
(EN)
A well bore completion tool includes an accelerometer having an accelerometer output representative of acceleration of the well bore completion tool. The well bore completion tool includes a signal conditioning device coupled to the accelerometer output and producing a conditioned accelerometer output. The well bore completion tool includes an uplink coupled to the conditioned accelerometer output.
(FR)
La présente invention concerne un outil de complétion de puits de forage qui comprend un accéléromètre qui a une sortie d'accéléromètre représentative de l'accélération de l'outil de complétion de puits de forage. L'outil de complétion d'alésage de puits comprend un dispositif de conditionnement de signal qui est couplé à la sortie d'accéléromètre et qui produit une sortie d'accéléromètre conditionnée. L'outil de complétion de puits de forage comprend une liaison montante couplée à la sortie d'accéléromètre conditionnée.
