Abstract The article discusses hydrodynamics of the reservoir fluid withdrawal from the promising drilled formation interval with the use of a jet pump installed in the internal cavity of the drill pipe string in the wellbore bottom-hole part. The hydrodynamic problem of fluid production is solved. The solution connects the dynamics of injected, recoverable and upward flows of the circulating system.
