Title (EN) METHODS OF REDUCING STRESS IN DOWNHOLE TOOLS
(FR) PROCÉDÉS DE RÉDUCTION DE CONTRAINTE DANS DES OUTILS D'EXTRACTION
Abstract: front page image
(EN)A method for reducing stress in a downhole tool. The method includes varying a temperature of the downhole tool by at least 5°C. Vibrational energy may be transferred to the downhole tool with a vibration device coupled to the downhole tool. The vibrational energy may cause the downhole tool to move with a frequency from about 10 Hz to about 5 kHz.
(FR)L'invention concerne un procédé de réduction de contrainte dans un outil d'extraction. Le procédé consiste à faire varier une température de l'outil d'extraction d'au moins 5°C. Une énergie de vibration peut être transférée à l'outil d'extraction avec un dispositif de vibration couplé à l'outil d'extraction. L'énergie de vibration peut amener l'outil d'extraction à se déplacer à une fréquence d'environ 10 Hz à environ 5 kHz.
