An energy-saving water injection pump aimed at high-energy consumption and low efficiency of the traditional water injection pump in the later stages of oilfield exploitation is proposed. The hydraulic pump is used as the main power source to control the movement of the piston through the mechanical reversing valve, thereby driving the plunger to move left and right, supercharging the water in the plunger cylinder. First, the structural parameters of the energy-saving water injection pump were determined. Then, dynamic analysis of the pump parts was carried out. The finite element simulation of the piston cylinder and the plunger cylinder showed that the structural strength meets the requirements. The hydraulic system dynamic simulation showed that the output pressure can reach the predetermined pressure. Finally, a field test was carried out in the Jiangsu Oilfield. The results show that the device can meet the water injection requirements of the oilfield.
