A downhole pump assembly for pumping formation water from a producing gas well. A hydraulic drive motor provides a driving force to operate a submersible pump. The drive motor has a drive fluid inlet and a drive fluid outlet. A drive fluid supply conduit extends from surface to the drive fluid inlet of the hydraulic drive motor. A drive fluid return conduit extends from the drive fluid outlet back to surface to facilitate a circulation of hydraulic drive fluid originating from surface through the hydraulic drive motor and back to surface.
Ensemble de pompe de fond de trou pour pomper l'eau d'une formation à partir d'un puits producteur de gaz. Un moteur d'entraînement hydraulique produit une force d'entraînement pour actionner une pompe submersible. Le moteur d'entraînement comporte une admission de fluide d'entraînement et un refoulement de fluide d'entraînement. Une conduite de fourniture de fluide d'entraînement s'étend de la surface à l'admission de fluide d'entraînement du moteur d'entraînement hydraulique. Une conduite de retour de fluide d'entraînement s'étend à partir du refoulement de fluide d'entraînement pour retourner à la surface afin de faciliter une circulation de fluide hydraulique provenant de la surface à travers le moteur d'entraînement hydraulique et retournant à la surface.
