摘　　要：:钢丝绳柔性抽油杆是一种特种密封钢丝绳的连续抽油杆。RS系列钢丝绳柔性抽油杆与普通D级抽油杆进行比较 ,抗拉强度高 1 .54倍 ,破断张力高 1 .2 0倍。在中原油田 1 0口井应用 ,单井泵效提高 1 4.7%。文中介绍柔性抽油杆的发展简况 ,RS系列柔性抽油杆的结构 ,特性及优点 。Wire line flexible pumping rod is a coiled rod with sealing wire line. RS series wire line flexible pumping rod compare with D level pumping rod,its tensile strength and destructive tension are higher.By application in 10 wells in Zhongyuan Oilfield,the results show that single well pump efficiency is increased by 14.7%.The paper presents the development of flexible pumping rod,and structure ,characteristics and advantages of RS series flexible pumping rod,meanwhile,evaluates wells selection condition and effictiveness of the flexible pumping rod in field application.
