| 摘要: |
| 为解决油田抽油系统开采原油效率低、能耗大等问题，以抽油机系统为研究对象，建立抽油机动力学模型与效率模型，并利用该数学模型计算出该抽油机悬点载荷示功图与效率，进而提出一种新的动力系统传动方案，即利用弹簧组存储抽油系统减速换向惯性能量，抽油系统换向后加速起动时能量释放.结果显示：加入弹簧储能装置的电动机减小了电机工作状态转换之间的冲击，大幅节省系统能量消耗.本设计的抽油系统弹簧储能装置能够显著减小电机扭矩波动，缩短启动时间，减小电机发热，延长电机寿命.对比传统往复式抽油机有明显的改善，节能率达到10.46%.

| Abstract: |
| In order to solve oilfield pumping system with the following disadvantages:low efficiency of crude exploitation, high energy consumption, etc. Kinetic and efficiency model of pumping system has been established to calculate the pumping rod load and efficiency. A new power system transmission solution has been proposed, which use spring group to store pumping system deceleration inertial energy. Spring group releases energy when pumping system changes direction. Adding spring energy storage device reduces the impact of electrical motors' working status switch, and saves system energy consumption substantially. Spring energy-storage device designed in this paper can reduce motor torque ripple, short start-up time, and reduce motor heating, extend motor life. Compared with traditional reciprocating pumping unit, the new-designed oil-pumping system has great improvement, the energy saving rate reaches 10.46%.
