摘要
介绍了柔性抽油杆的试制和对抗拉强度、弹性模量和疲劳寿命的测试结果。测试结果表明，柔性抽油杆的综合性能高于钢质抽油杆。油田试用结果表明，对它的操作和安装都较方便，可以连续进行起下井操作；由于无接箍，消除了活塞效应，泵效提高了，节能效果明显，具有良好的使用前景。
Abstract The articlc is introduced a process for producing flexible sucker rod and the results of testing in tension strength,modulus of elasticity and fatigue strength for the flexible sucker rod.This new sucker rod is superior in mechanical property and other properties,comparing with sucker rods.In oil well servieing operation it can be take up and take off continually,as it has smooth surface.There isn 竧 any wax sediment on it.The new type sucker rod as a oil pump sucker rod can get very high pump efficiency and lower consumption of power.This product will have good future in application.
