摘　　要：针对低渗透、低产量油井,设计了柔性连续抽油杆提捞式抽油机。介绍了该抽油机主要结构和工作原理,并推导了系统输入功率、输出功率以及系统效率的计算公式。给出了常规抽油机井和提捞式抽油机井能耗和系统效率的计算实例。结果表明,在相同油井条件下,与常规抽油机-抽油泵系统相比,提捞式抽油机系统效率较高,耗电量较低。Aiming at the low permeability,low output oil well,the flexible continuous sucker rod bailing pumping unit is designed.Its work principle and main structure are introduced.Based on its work principle,the input power,output power and system efficiency calculation formula are deduced.The calculation example of energy consumption and system efficiency is given about conventional and bailing pumping unit oil well.The calculation result showed that system efficiency of bailing pumping unit well is higher and the electricity consumption is lower than that of conventional pumping unit well.
