Detailed content was followed： Firstly, the development overview of domestic and international pumping unit, the status quo of the reconstruction of conventional beam pumping unit were discussed, and put forward the main contents of this paper. Secondly, the kinematics, the dynamics and the reducer’s torque characteristics of the conventional beam pumping unit were studied deeply to provide a theoretical basis for optimization of reconstruction projects. Thirdly, system efficiency of the pumping unit was studied, the factors affecting the system efficiency, and the measures improving the system efficiency were pointed out, the energy consumption and the equilibrium theories of the pumping unit were analyzed, and the energy-saving mechanism of the pumping unit was studied, which provided theoretical support for the design of the reconstruction projects. Fourthly, selected the typical pumping unit, the typical well conditions to calculate, got the parameters of the pumping unit, such as the horse-head load, the net torque of reduce ,the loop mean square torque
