An improved hydraulic downhole oil recovery system that incorporates an above ground hydraulic pumping unit and a submersible, bi-directional, reciprocating downhole hydraulic slave cylinder-based pumping unit. Water, rather than hydraulic fluid, is responsible for actuating the reciprocating downhole pump unit. The water is transferred through the system using seamless, coil tubing.
L'invention concerne un système de récupération de pétrole hydraulique de fond amélioré comprenant une unité de pompage hydraulique en surface ainsi qu'une unité de pompage de fond à mouvement alternatif et à cylindre esclave hydraulique qui est submersible et bidirectionnelle. On utilise de l'eau, plutôt qu'un autre liquide hydraulique, pour actionner l'unité de pompage de fond à mouvement alternatif. L'eau est transférée à travers le système au moyen d'un tube de production concentrique continu.
