METHOD FOR EXTRACTING OIL AND PUMP-EJECTOR SYSTEM FOR ITS REALIZATION Russian patent published in 2004 - IPC

Abstract RU 2238443 C1

FIELD: oil extractive industry.

SUBSTANCE: method includes lowering flow apparatus into well, forcing of working liquid by force pump into nozzle of flow apparatus, extraction of well fluid and gas by flow apparatus onto surface and separation of free gas and hard phase from liquid on the surface. After raising liquid and gas onto surface centrifugal separation of hard phase from working and well liquids is performed. Portion of flow of well liquid is fed together with separated hard phase to outlet line. Working and remaining well liquid with free gas is directed to collecting tank, where centrifugal separation of free gas is performed before inlet of working fluid to input of force pump placed in collecting tank, while feeding separated free gas and remaining well liquid from collecting tank to output line.

EFFECT: higher reliability, lower material costs, lower assemblage and maintenance costs.
