摘　　要：文章通过对无油管采油系统工作时受力分析,采用变形能原理,推导出空心抽油杆扶正器的安放间距。现场应用表明,该方法可有效防止空心抽油杆与油管的偏磨,降低对套管的损伤,为国内从事该技术应用的同行提供一种新的方法。This article works out the placing interval of hollow sucker rod centralizer through the stress analysis when non-drill tubing extraction system works, using distortion energy principle. The field application indicates this method can effectively prevent the partial friction between hollow oil extraction rod and the drill tubing and reduce the damage to the drive-pipe. So a new method is provided to the domestic colleagues who are engaged in this technical application field.
