抽油机采用抽油杆向井下泵传递动力,杆管接触时,相对运动造成抽油杆与油管的磨损,称为偏磨。偏磨使抽油杆磨损,降低了抽油杆的强度,造成抽油杆断裂,磨穿油管壁,影响油井正常工作,给油田带来较大的经济损失。因此探索应用新技术、新工艺减少偏磨腐蚀,是降低采油成本的有效措施之一。 The pumping unit uses a sucker rod to transmit power to the downhole pump. When the rod tube contacts, the relative movement causes the sucker rod and tubing to wear, which is called partial wear. Partial wear abrasion sucker rod, reducing the strength of the sucker rod, causing the sucker rod fracture, worn through the wall of the oil well, affecting the normal operation of the well, bringing greater economic losses to the oil field. Therefore, exploration and application of new technologies and new processes to reduce partial wear and tear are one of the effective measures to reduce oil recovery costs.
