摘　　要：在石油开采过程中,有杆泵是目前应用最广泛的人工举升方法之一。有杆采油系统在石油和天然气行业中被认为是一项成熟的技术,具有易于应用、使用成本低等优势,在世界范围内应用普遍。但在实际运行过程中,抽油杆与油管之间的偏磨问题较为严重,由此带来的经济损失较大。通过对抽油杆产生偏磨的原因进行分析,总结了五大类最新的防偏磨技术,并提出了现有技术的发展方向,以期对生产实践起到一定的指导作用。Rod pump is one of the most widely used artificial lifting methods in the process of oil exploitation.Sucker rod pumps are considered a well-established technology in the oil and gas industry and thus are easy to apply,very common worldwide,and low in capital and operational costs.However,in the actual operation process,the problem of eccentric wear between the rod and the tubing is more serious,which brings relatively large economic losses.The causes of the partial-wear were analyzed and five kinds of latest anti-eccentric wear technology were summarized,hoping to play a certain guiding role in production practice.By analyzing the causes of eccentric wear on pumping rods,five latest anti-eccentric wear technologies are summarized,and the development direction of technologies is proposed,in order to provide guidance for production practice.
