Abstract

La présente invention concerne un appareil et un procédé pour pomper des fluides, tels que de l'eau et/ou des hydrocarbures, à partir d'une formation souterraine ou d'un réservoir, comprenant une pompe à tige linéaire ayant un agencement de crémaillère mécanique et d'entraînement de pignon, conçue pour être fixée à un mécanisme de pompage, tel que la tige polie située sur la partie supérieure d'une corde de tige dans un puits d'hydrocarbure. L'engrenage de crémaillère de l'agencement de la crémaillère et d'entraînement de pignon est conçu pour être connecté à la tige polie et pour se déplacer avec elle. L'engrenage de pignon ne translate pas avec l'engrenage de crémaillère et est entraîné par un moteur réversible permettant d'effectuer un mouvement de va-et-vient de haut en bas de l'engrenage de crémaillère et du mécanisme de pompage. Certains modes de réalisation de l'invention comprennent un agencement de contre-balancier à gaz compressible. Certains modes de réalisation de l'invention comprennent un entraînement électronique configuré pour utiliser le courant électrique généré par le moteur pendant une partie du cycle de pompage.
