摘　　要：针对大庆油田螺杆泵现有扶正器存在的摩擦阻力大、寿命短等问题,研制了能够自润滑、自旋转的新型抽油杆扶正器,包括与抽油杆连接的接箍式和安装于杆体上的杆轴式2种结构。特点是利用扶正环内部轴承固体润滑方式来减小扶正摩擦阻力,外部耐磨扶正环相对于油管运动少而降低磨损和磨阻,能够在保证扶正效果的同时降低摩擦阻力,延长系统寿命。On the basis of analysis of the current centralizer＇s friction and rod dropped problems in Daqing oilfield,a new-type of centralizers was developed which can be self-lubricating and self-spinning.Two kinds of construction are introduced：coupling connection and thermal setting rod connection that stabilizer has an inner solid lubricating bearing and outer resistance synthetic nylon.It can reduce rod eccentric friction and wear and increase the system life.
