PUMPING DEVICE FOR PUMPING OIL PRODUCT wells with high GOR

摘要

The present invention relates to the field of oil production, namely, to the infield pumping oil, and in particular to a pump device for pumping the production of oil wells with high GOR. Pumping device comprises an open-vortex pump unit is a self-priming type adapted to discharge the fluid which is a gas-liquid mixture, the bypass line, the inlet of which is located upstream of the pump unit and the outlet is located downstream from the pump unit, at least one valve disposed in the bypass line, an ejector disposed in the bypass line downstream of the at least one valve disposed in the bypass line and configured to reg lation of fluid flow through the bypass line and through the pump unit, the blast inlet ejector fluidly connected through portion of the bypass line to the main line at a position downstream of the pump unit and upstream of the junction of the main line and release the bypass line, the suction ejector inlet fluidly connected by a bypass line portion with an inlet bypass line and release ejector fluidly connected by a bypass line portion with the release bayp waist line. 13 ZP f-ly
