Title (EN) DOWNHOLE TENSION SENSING APPARATUS
(FR) APPAREIL DE DÉTECTION DE TENSION DE FOND DE TROU
Abstract:
(EN) An apparatus having a downhole tool for coupling between opposing portions of a downhole tool string. The downhole tool includes a load cell (206) connected along a tension-bearing member (234) of the downhole tool and operable to generate a signal indicative of tension applied to the downhole tool. The downhole tool further comprises an electronic device (204) operable to receive the signal indicative of the tension. The apparatus further comprises a perforating tool for coupling within the tool string and operable to perforate at least a portion of a subterranean formation surrounding a wellbore.
(FR) Cette invention concerne un appareil comprenant un outil de fond destiné à être monté entre des parties opposées d'un train d'outils de fond. L'outil de fond comprend une cellule de charge (206) montée le long d'un élément de tension (234) de l'outil de fond et conçue pour produire un signal indiquant la tension appliquée à l'outil de fond. L'outil de fond comprend en outre un dispositif électronique (204) permettant de recevoir le signal indiquant la tension. L'appareil comprend en outre un outil de perforation à monter dans le train d'outils et apte à perforer au moins une partie d'une formation souterraine entourant un puits de forage.
