Abstract
Dispositif (60) de régulation de débit servant à injecter du gaz dans une colonne de production pour rétablir de la pression et réduire les pertes par friction, si bien que le régime critique peut être atteint à des baisses de pression inférieures et à une pression de production plus élevée. Ledit dispositif comporte un logement, des orifices d'entrée (54), un museau (61) avec une soupape de retenue (65), des orifices de sortie (64) et une tuyère (34) ayant des première et seconde extrémités, et un passage de fluide entre ces deux extrémités, ainsi qu'un venturi doté de première et seconde extrémités. La première extrémité de la partie venturi est placée adjacente à la seconde extrémité de la tuyère. La voie d'écoulement du venturi est alignée coaxialement avec la voie d'écoulement de la tuyère de manière à produire une voie d'écoulement continue à travers ces deux éléments. Un dispositif de régulation de débit de ce type, dont la performance de débit de gaz est indépendante de la pression dans les conduits, même lorsque ladite pression atteint 80 % à 93 % de la pression du tubage, peut être utilisé pour augmenter la capacité de production, améliorer l'efficacité d'extraction et éliminer ou supprimer l'instabilité dans des puits d'extraction à l'air à flux continu.
