Abstract

A hydraulic jet pump for transference of a fluid medium and method for use of the same are disclosed. In one embodiment of the hydraulic jet pump, a power fluid inlet adapter communicates through a jet nozzle to a mixing tube along a power fluid inlet flow path. In a first configuration, an axial diverter member traverses the jet nozzle and the diffusing chamber. In a second configuration, the mixing tube has an inlet that is axially aligned with the jet nozzle. In a third configuration, the mixing tube has at least two inlets, one that is axially aligned with the jet nozzle and another that is angularly offset from the alignment of the jet nozzle and the mixing tube. One of the three configurations is selected prior to downhole deployment of hydraulic jet pump.
