下寺湾油田90%以上的抽油井为定向斜井,普遍存在管杆偏磨现象,偏磨已成为抽油井检泵的主要原因,严重影响了油田正常生产。通过对该油田管杆偏磨的原因分析,找出了影响杆管偏磨的主要因素,有针对性地采取防偏磨措施,减缓了偏磨程度,延长了检泵周期。 More than 90% of the pumping wells in the Xiansiwan oil field are directional inclined wells, and eccentric wear of the pipe rod is common. Partial abrasion has become the main reason for pumping wells and seriously affects the normal production of the oilfield. By analyzing the reason of partial wear of the pipe rod in the oilfield, the main factors affecting the partial wear of the pipe rod were found out, and the anti-eccentric wear measures were taken in order to reduce the degree of partial abrasion and prolong the inspection cycle.
