High-viscosity oil recovery mechanism

Authors: B.A. Erka (TNNC LLC), A.A. Dvinin (Tyumen State Oil and Gas University)

Vane pump, which working blades have direct contact with the reservoir fluid, is offered to use for high-viscosity oil lif - ting. It is shown, that the pump can transfer downhole fluid with the high content of mechanical impurity and gas. It is noted, that small dimensions of the pump allow to use it in wells with high rate of hole deviation change and in horizontal wells.
