抽油机光杆现场修复的研究与应用

Research and Application of Spot Rod Pole Repair in Field

抽油机光杆是抽油机连接深井泵的重要构件,在使用过程中,遭受不同程度的腐蚀、磨损、磕碰,以及循环的轴向、切向的交变应力等,在光杆表面出现沟槽、变形、剥落坑等极为明显的磨损,继续使用会造成井口跑油、跑水,不仅增加管理难度也严重污染环境。为了保证油田的正常生产和安全,每年都会更新和淘汰一部分光杆。为节约成本,一般采取在现场对旧抽油光杆进行修复,对符合一定要求的旧光杆继续使用,达不到要求的淘汰。

The sucker rod of pumping unit is an important component connected to the deep well pump in the pumping unit.During operation, it suffers various degrees of corrosion, wear, bump and cyclic axial and tangential alternating stress, etc., Deformation, peeling pits and other extremely obvious wear and tear, continue to use will cause the wellhead run oil, running water, not only increase the difficulty of management also seriously pollute the environment.ln order to ensure the normal production and safety of the oilfield, some polished rods are updated and eliminated every year.In order to save the cost, the old sunshade rod is usually repaired on the spot, and the old sunshade rod that meets certain requirements is used continuously to meet the specific requirements and can not be selected and eliminated.
