直井抽油杆柱磨损机理及原因

The abrasion mechanism and cause analysis for straight well rod string

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 abrasion of the rod string occurs because of the friction between the rod string and the tube. Several causes for the bending due to the contact friction of the two for the bend are studied. The abrasion mechanism is analyzed. The kind of abrasion is adhesive abrasion. Some factors that affect the degree of the abrasion is discussed, and the corresponding preventing-abrasion methods are given. The methods can be used to prevent the rod string abrasion in oil fields.
