Gas turbine driven oil lifting device represents a device for increasing the quantity of oil obtained in the unit of time and the percentage of total amount obtained from oil bearing geological deposits. The device is installed in technical column (1) and consists of sections (12) and (18), separated by a bypass packer (11), on which gas turbine (9) is fixed by coupling (14), and tubing (17) with valves (3), (4), (6), (8) is fixed to the turbine (9) by coupling (15). Above the gas turbine (9) a check valve (16) is installed in the tubing (17). Parallel with the tubing (17), a supply tube of the turbine (2) is fixed by couplings (5) and (19), and is by its bottom end connected to the opening (20) at the upper head (34) of the gas turbine (9) by a flexible hose (7). The device may operate continually and periodically. It may be applied for recovery of liquids from all the liquid bearing geological deposits, having insufficient pressure for natural flow.

Cette invention se rapporte à un dispositif d'extraction de pétrole entraîné par une turbine à gaz, qui constitue un dispositif permettant d'accroître la quantité de pétrole obtenue par unité de temps et le pourcentage de quantité totale obtenue de dépôts géologiques pétrolifères. Le dispositif est installé dans la colonne technique (1) et comprend des sections (12 et 18) séparées par un garnissage de dérivation (11), sur lequel une turbine à gaz (9) est fixée par couplage (14) et un tubage (17) pourvu de soupapes (3, 4, 6, 8) est fixé à la turbine (9) par couplage (15). Une soupape de non-retour (16) est montée dans le tubage (17) au-dessus de la turbine à gaz (9). Un tube d'alimentation de la turbine (2) est fixé par des couplages (5 et 19) parallèlement au tubage (17), et il est raccordé par son extrémité inférieure à l'ouverture (20) située au niveau de la tête supérieure (34) de la turbine à gaz (9) par un tuyau souple (7). Ce dispositif peut fonctionner en continu et périodiquement. Il peut servir à récupérer des liquides de tous les dépôts géologiques pétrolifères liquides, ayant une pression suffisante pour l'écoulement naturel.
