摘要/Abstract

摘要：

现役的游梁式抽油机耗电量超过油田生产总用电量的50%，其总效率往往低于30%，抽油机系统的效率低下造成了电能的较大浪费，而游梁式抽油机的工作原理及结构特点有利于采用飞轮储能装置提高其效率。本工作设计了适用于游梁式抽油机的飞轮储能系统，建立了抽油机动力学仿真模型，搭建了相应的实验测试平台，采用仿真分析和实验研究相结合的方法验证了储能系统的可行性，并探讨了加入储能飞轮后对抽油机能耗的影响。实验结果表明：储能飞轮在上冲程释放能量，在下冲程吸收能量；加入飞轮后电机功率曲线峰值由782 W减小为620 W，电机的谷值功率由-448 W变为-359 W，即降低峰值和增加谷值，使电机运行更加平稳。最后通过实验对比了仿真和测试数据，验证抽油机飞轮储能系统的节能效果：在冲程冲次不变，负载相近的情况下，实验所得结果与仿真分析的数据结果趋近，游梁式抽油机飞轮储能装置能节约15.7%的能量，具有明显节能效果，为游梁式抽油机应用飞轮储能系统实现节能降耗提供了参考。

Abstract:

The current power consumption of beam pumping units in service exceeds 50% of the total power consumption of oil field production, and their overall efficiency is often less than 30%. The low efficiency of the pumping unit system results in a significant waste of electricity. The operating principle and structural characteristics of the beam pumping unit allow for the incorporation of flywheel energy-storage devices to improve their efficiency. A flywheel energy-storage system suitable for beam pumping units was designed, a pumping unit dynamics simulation model was established, and a corresponding experimental test platform was built to validate the feasibility of the energy-storage systems using simulation analysis and experimental research, and the effect of adding energy-storage flywheel on the pumping unit's energy consumption was discussed. The results indicate that the energy-storage flywheel releases energy during the upper stroke and absorbs it during the lower stroke. With the addition of the flywheel, the peak value of the motor power curve decreases from 646 to 517 W, whereas the valley power of the motor changes from -361 to -296 W, implying that the peak value decreases and the valley value increases, resulting in a more smooth operation of the motor. Finally, the pumping unit's energy-saving effect was verified by comparing the experimental data. The result shows that under the condition of constant stroke times and similar load, the experimental result is close to the conclusion of the simulation analysis. Adding a flywheel energy-storage device saves 15.7% of energy and has an obvious energy-saving effect, and it serves as a reference for the use of flywheel energy-storage systems in beam pumping units to achieve energy saving and consumption reduction.
