Abstract: According to the characteristics of the small spacing of cluster wells, this paper designs a double-well mutual balance hydraulic pumping unit. One pumping unit is used for two wells, and it achieves interactive balance pumping through two balanced hydraulic cylinders. The hydraulic system is simulated by AMESim software. The simulation results are in good agreement with the design curve, which proves the designed pumping unit has excellent working performance.
