The purpose of this paper is to analyze the power efficiency of oil well systems with sucker rod pumping units. For this study a chain-drive of HRC 80-6-02 type and a similar performance drive HRC 80-6-02 balancer pumping unit were selected. Based on the analysis of the data, a conclusion was made that the power consumption for production of oil using ESP units is much higher due to a low coefficient of performance (COP) and significant losses in the submerged electric-driven pump. The analysis showed that for a half cycle of operation, i.e. per one stroke, the power consumption by a jack-pump was 15-20% higher than that of the chain drive. It is concluded that the chain drive is superior in many aspects of sucker-rod pumping units operation and may be the most effective replacement for ESP units, as well as for units with walking-beam jack pumps.
