摘　　要：针对目前使用的有杆抽油系统存在的各种问题,提出一种无杆抽油系统,即,井下电潜式往复泵举升系统。对该举升系统进行了设计,并分析了其工作原理。这种举升系统以直线电机为井下动力源,不使用抽油杆,有效地减小偏磨、能耗等问题,提高了综合效益。For the problems of suck rod pumping system which is used currently, one of the rodless downhole pumping systems is proposed, that is reciprocal pump system working as electric submersible pump. Lifting system is designed, and operating principle is analyzed. The linear electric motor is downhole power source of the lifting system without using sucker rod. The technique can save energy, reduce lopsided wear and raise the combined benefit.
