MATHEMATICAL MODEL OF JET PUMP OPERATION IN TANDEM OIL WELL PUMPING UNIT

Usability of tandem pumping units in in-situ leaching technology of uranium production is justified. The proposed tandem scheme is advantageous for reduction in load on electric submersible pump and for feasible considerable increase in productivity of uranium-pregnant solution pumping. The tandem pump is less sensitive towards different dynamic conditions, operates effectively even when pregnant solution contains sand fraction, and has higher performance index. The studies used analytical and experimental calculation methods. As a result, based on the Bernoulli equation, the mathematical model is constructed for operation of jet pumps and its key elements: high-pressure nozzle, receiving chamber, mixing chamber and diffuser. The modeling procedure for joint operation of electric submersible and jet pumps allows prompt and sufficiently accurate selection of optimal design parameters of jet pump for the tandem pumping unit operation in specific real condition of wells with different dynamic fluid levels, as well as determination of performance index, optimized ejection coefficient and cavitation-free mode. Recommendations on jet pump design are given.
