Beam pumping unit is the uppermost artificial lifting equipment in the oilfield exploitation. In order to reduce its energy consumption and to cut down the oil production costs, many manufacturers have developed a lot of types of the energy-saving pumping unit. With different energy-saving principle, the energy-saving effects are quite different. It is becoming very important how to justly and reasonably evaluate the energy-saving effect of a pumping unit. Hydrodynamic simulated experiment well is used to compare the energy-saving effects of four types of pumping units. In the process of the experiments, water is taken as the medium, offset pumping unit is as the reference body, system efficiency and electricity-saving ratio is as the evaluating goal and all the experiments are executed at the same condition. The relative curves of the lifting height with the system efficiency and the electricity-saving ratio are drawn for the four types of the pumping units. Testing results indicate that the double horse-head pumping unit has the best effect, and then the compound-balanced pumping unit with downward beam balance weight. According to the comparative results, it is put forward the pumping unit selecting suggestions.
