Title (EN) DOWNHOLE WELLBORE HIGH POWER LASER HEATING AND FRACTURING STIMULATION AND METHODS
(FR) STIMULATION ET PROCÉDÉS DE FRACTURATION ET DE CHAUFFAGE AU LASER DE HAUTE PUISSANCE DE PUITS DE FORAGE DE FOND DE TROU
Abstract:
(EN) A system for fracturing a formation (40) comprising a laser surface unit (50) configured to generate a laser beam, a power cable (65) electrically connected to a power source (60), a fluid line (75) connected to a cooling fluid source (70), a protective shaft (80) extending into the wellbore (10), the motor (200) configured to rotate a motor shaft (210), and the thermal shocking tool (300) comprising a protective case (305), a rotational shaft (310) connected to the motor shaft, the laser delivery device (330) extending from the rotational shaft configured to transform the laser beam to a focused laser beam operable to increase the temperature of the formation to a fracture temperature, and the cooling system (320) extending from the rotational shaft opposite the laser delivery device configured to introduce the cooling fluid stream onto the formation such that the cooling fluid stream reduces the temperature of the formation such that thermal shocks occur and fractures are formed in the formation.
(FR) L'invention concerne un système de fracturation d'une formation (40), ledit système comprenant une unité de surface de laser (50) conçue pour générer un faisceau laser, un câble d'alimentation (65) connecté électriquement à une source d'alimentation (60), une conduite de fluide (75) reliée à une source de fluide de refroidissement (70), un arbre de protection (80) s'étendant dans le puits de forage (10), le moteur (200) étant conçu pour faire tourner un arbre de moteur (210), et l'outil de choc thermique (300) comprenant un boîtier de protection (305), un arbre rotatif (310) relié à l'arbre moteur, le dispositif d'émission de laser (330) s'étendant à partir de l'arbre rotatif conçu pour transformer le faisceau laser en un faisceau laser focalisé apte à augmenter la température de la formation jusqu'à une température de fracture, et le système de refroidissement (320) s'étendant à partir de l'arbre rotatif en face du dispositif d'émission de laser conçu pour introduire le flux de fluide de refroidissement sur la formation de telle sorte que le flux de fluide de refroidissement réduise la température de la formation, de telle sorte que des chocs thermiques se produisent et que des fractures se forment dans la formation.
