抽油杆柱,只要根据实际情况和使用经验正确设计、按制造厂推荐的方法运输装卸、采用正确的上卸扣方法起下、进行正确抽油作业和有效控制井下腐蚀,就能延长使用寿命,从而取得满意的经济效果。 使用寿命取决于对引起过早失效的各种条件的控制,以及取决于对过早失效原因的早期确定和对所存在问题的处理。 Sucker rod, as long as the correct design based on the actual situation and experience, transport methods according to the manufacturer’s handling loading and unloading, using the correct method on the shackle down, the right sucker operation and effective control of underground corrosion, you can extend the service life , So as to obtain satisfactory economic results. The useful life depends on the control over the conditions that cause premature failure and on the early determination of the cause of the premature failure and the treatment of the problems that exist.
