摘　　要：为了解决螺杆泵采油井杆柱有效扶正问题,研制开发了卡装式抽油杆扶正器。它相对接头连接式抽油杆扶正器具有结构简单、成本低、易于安装使用,能够根据生产需要布置在抽油杆柱任意位置的特点。卡装式抽油杆扶正器现已用于400多口井,使用效果良好。New-type centralizers clamped on sucker rod string is developed to stabilize the sucker rod string in a screw pump oil production system.In contrast to conventional centralizers screwed on sucker rod, new-type centralizers have several advantages of simple structure,ease use, less cost and any positions spaced on the rod string. New-type centralizers have been used in over 400 oil wells and have acquired better effects.
