PRACTICAL APPLICATIONS OF PUMP EFFICIENCY COMPUTATION METHOD OF PUMPING UNIT

In order to verify the computation method of pump efficiency, we record tons thousand data in some production wells in Daqing oilfield in recent three years,and then calculate the efficiency of pump and its down hole losses using the said method. Based on calculation and anaiysis results, we adjust the working systems of some production wells, and then verify the achievements in theoretical research. The field test results show that the pump efficiency computation method is correct, the downhole losses calculated by the theoretic model accord with reality, and the measures adopted in pumping wells are effective.
