Title
(EN) A DOWNHOLE POWER GENERATING APPARATUS
(FR) APPAREIL GÉNÉRATEUR D'ÉNERGIE DE FOND DE PUITS
Abstract
(EN) A downhole power generating apparatus comprising a low pressure chamber, a floating piston, a high pressure chamber, a first flow through path, a second flow through path, and a turbine. The low pressure chamber includes an inlet and an outlet for cycling tubing fluid. The floating piston separates the low pressure chamber into an upper and lower section. The floating piston is cyclically responsive to a cycle of tubing fluid and another cycle of tubing fluid. The first flow through path couples a fluid from the lower section of the low pressure chamber to the high pressure chamber in response to a cyclical response of the floating piston. The second flow through path couples the fluid from the high pressure chamber to the lower section in response to another cyclical response of the floating piston.
(FR) La présente invention concerne un appareil générateur d'énergie de fond de puits comprenant une chambre basse pression, un piston flottant, une chambre haute pression, un premier trajet à écoulement continu, un second trajet à écoulement continu et une turbine. La chambre basse pression comprend une entrée et une sortie pour le cyclage d'un fluide de colonne de production. Le piston flottant sépare la chambre basse pression en une section supérieure et une section inférieure. Le piston flottant est cycliquement sensible à un cycle de fluide de colonne de production et à un autre cycle de fluide de colonne de production. Le premier trajet à écoulement continu raccorde un fluide de la section inférieure de la chambre basse pression à la chambre haute pression en réponse à une réponse cyclique du piston flottant. Le second trajet à écoulement continu raccorde le fluide de la chambre haute pression à la section inférieure en réponse à une autre réponse cyclique du piston flottant.
