The structure of the equations of the pressure-flow characteristics of the high-pressure jet pump is supplemented with a component that determines the additional pressure caused by the influence of eddy currents during the asymmetric rotation of the ejection system around the axis of the well. On the basis of the joint solution of the Bernoulli equations, the preservation of the integrity of the moving medium, the momentum and moment of movement of the mixed flows, a relationship was obtained for the analytical determination of the additional dynamic pressure created by the rotation of an eccentrically placed jet pump in the well. In the process of researching the resulting equation, the extreme nature of the growth of the pressure-flow and energy characteristics of the overbite ejection system was established. The increase in pressure and efficiency caused by the asymmetric rotation of the over-chisel ejection system is inversely proportional to the value of the main geometric parameter of the jet pump.
