The present invention relates to an oil pumping machine used in oil field, in particular to an energy-saving beam oil pumping machine, which solves the problem that the prior beam oil pumping machine is difficult to achieve the energy saving due to the restrictions of the work principle and structure, in particular to the limited realization of operating mechanism. The present invention includes a central bracket, a beam, an oil pumping rod and a crank fixed with a balanced block on one end and driven by a motor and a reducer. One end of the beam is provided with a donkey head and the other end is connected with the crank through a connecting rod; an energy storage and utilization device is arranged below the upper beam of the central bracket; the energy storage and utilization device includes a support fixed body arranged on the central bracket, a support rod supported by the support fixed body reciprocating along a fixed direction against the support fixed body, a regulating jacket fixed on the support rod and a spring arranged between the regulating jacket and the fixed body on the support rod. The present invention with simple and reasonable structure and good energy-saving effect is suitable for all balanced beam oil pumping machines.
