In order to meet the need of oil lifting with high efficiency and low cost, a well condition self-adaptive pumping unit has been developed. This new intelligent unit can adjust its pumping speed automatically according to the well condition by the utility of the advanced switched reluctance drive and microcomputer. This article introduces its mechanical structure, principle of intelligent control and law of motion. Field test demonstrates that the unit runs reliably with accurate balance and minor stroke loss, and its pumping speed can be adjusted automatically to fit the change of the well condition. Relevant data shows that the efficiency of the pumping system is enhanced by 48% and 44.46% of energy is saved compared with the previous beam pumping unit worked on the same oil well.
