Simulation of formation fluid withdrawal hydrodynamics using a downhole jet pump when studying the productive formation while well drilling

Abstract

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.
