Key words: well, oil pump, delivery coefficient, water cut, power consumption.
The paper presents the results of field studies of production wells equipped with oil pumps. For Sibirskoye and Unvinskoye oilfields’ wells (Perm region) the influence of technological parameters on unit energy costs on the rise of liquid and oil from the well is assessed. The authors noted that rising water cut leads to a significant decrease in efficiency of oil production. The subject reflects the influence of the specific energy consumption in oil pump, performance immersion pump under the dynamic level and rate of flow.
