| 摘 要： | 减载器是采油井内配置的一种井下工具,可以通过自身产生的液压反馈力来降低抽油机驴头悬点载荷和抽油杆应力。加装减载器后,使有杆抽油系统的动力特性发生改变,原有系统平衡被打破。根据有杆抽油系统运动规律和平衡准则,对抽油系统及平衡重力进行分析。将理论计算与实际工况相结合,通过数值分析计算,对系统平衡进行调节,使有杆抽油系统能耗降低,达到节约生产成本、提高经济效益的目的。

| Abstract: | Load reducer is a subsurface tool in the oil well.The load reducer can reduce sucker rod stress and polished rod load of pumping unit horse head by hydraulic pressure.The power characteristics and the balance of sucker-rod pumping system were changed with the reduced force produced by the load reducer.According to the system motion law and the balance principle,the pumping system and the counter weight was analyzed with theory.The theoretical calculation combining with the actual working condition,the system balance was adjusted by the result of numerical analysis again.As a result,the energy consumption of rod pumping system is reduced,the production cost is saved and the economic efficiency is improved. |
