At present the operation of wells in case of a periodic mode of operation is becoming more and more popular. At the same time, there is a necessity of optimizing and determining the modes of accumulation and pumping of fluid from the well. The periodic operation of wells equipped by sucker-rod pumps driven by a beam pumping unit is poorly studied and requires additional research to optimize it. The authors of the article present a method for calculating the efficiency and power consumption of an electric motor in case of a cyclically variable load on the crank shaft of a beam pumping unit, taking into account the load factor of the electric motor and the shape coefficient of the loading line. The selection of deep-pumping equipment in the ESTP software is carried out for a well equipped with a sucker-rod pump driven by a beam pumping unit and a change in the dynamic level is simulated during the periodic operation of the well. As a result, an acceptable change of the dynamic level for 1, 3, 4, 5, 6 and 7 oscillation frequencies of the drive per minute was obtained in accordance with the change of the electric motor power consumption and the permissible imbalance of the electric motor power consumption. The maximum permissible changes of the dynamic level are observed at 3, 4 oscillations per minute and are equal to 200 meters. With an increase of the number of drive oscillations from 4 to 7, there is a decrease of the maximum permissible change in the dynamic level to 140 meters.
