探讨了抽油杆柱的磨损机理 ,研究了抽油杆柱与油管由于弯曲而相互接触摩擦的原因 ,结果表明 ,抽油杆柱与油管的磨损属于粘着磨损 .分析了影响粘着磨损程度的几种因素 ,并提出了相应的防止磨损措施 ,为现场采取防止抽油杆柱磨损措施提供了理论指导 .
The wear mechanism of sucker rod string was discussed, and the reason of contact friction between sucker rod string and tubing due to bending was studied. The results show that the wear of sucker rod string and tubing belongs to adhesive wear. And put forward the corresponding measures to prevent wear and provide theoretical guidance for the measures taken to prevent the sucker rod column from being worn in the field.
