摘　　要：针对现有游梁式抽油机能耗大、能效低状况,提出一种新型节能液压抽油机,并对影响抽油机能耗和性能的关键参数进行优化设计。基于AMESim平台搭建了所提抽油机仿真模型,将关键参数分为主要参数和非主要参数,采用遗传算法分步对主要参数和非主要参数进行优化设计,并通过理论计算分析和验证所得优化结果;其次,基于优化值对抽油杆位移进行闭环控制来调节抽油杆的速度特性,以减小换向产生的冲击振动。为验证优化结果对降低电动机功率的效果以及所提抽油机的节能优势,进行了多组仿真对比分析,结果表明:优化结果下电动机功率是保证系统性能的最小功率,且功率约为无能量回收液压抽油机的25%,节能效果显著。The existing beam pumping units are low energy efficiency and cost much energy,so an energy-saving hydraulic pumping unit was proposed,key parameters affecting the pumping unit energy consumption and performance were optimized.Pumping unit simulation model was built based on AMESim platform.The key parameters were divided into main parameters and non main parameters,which were optimized step by step with genetic algorithm,optimization results were analyzed and verified by theoretical calculation.Secondly,a closed-loop control of sucker rod displacement was done to adjust sucker rod speed characteristics with optimization results,which can reduce impact vibration during reversing.To verify the optimization results effect on reducing motor power and energy saving advantage,several groups of simulation and comparative analysis were carried out,the results show that:with optimization results,motor power is the minimum power to ensure the system performance,which is about 25%of that of hydraulic pumping unit without energy recovery.
