A new design scheme of energy-saving hydraulic pumping unit was put forward on the basis of relevant research to hydraulic pumping unit. Adopting balanced structure of Double Wells makes the falling potential energy of the sucker rod at one side supply power for rising of the sucker rod at the other side, which decreases the power of installation and realizes continuous pumping oil. Utilizing the tech-nology of load sensing and proportional control makes the pressure and flow meet the requirement of load simultaneously and adjust adap-tively in real time, which reaches higher precision of control and brings remarkable effect of energy-saving.
