我国空心抽油杆的制造与应用

    Domestic Manufacture and Application of Hollow Sucker Rod

    • 摘要: 介绍了国内空心抽油杆的主要结构和制造工艺,分析了空心抽油杆在热洗清蜡、掺稀采油、电加热采油、分层注水、排液采气5个方面的应用工艺。分析认为:直接连接式将成为空心抽油杆结构形式的发展方向;锻造成形与摩擦焊接+形变热处理这两种工艺,将成为国内空心抽油杆制造的主要方法;空心抽油杆的系列应用工艺将会成为国内稠油油田、高含蜡油田、天然气田开发的可靠方法。

       

      Abstract: Described in the article are the main structure of and the manufacturing process for the home-made hollow sucker rod.And analyzed are the five major applied processes of the said rod,i.e.,hot-washing of paraffin,dilute oil production,electric heating oil production,separate layer injection,and drainage gas recovery.The analysis result leads to such a conclusion that the direct connection type will become the development trend of the hollow sucker rod structure type;and for domestically manufacturing the sucker rod,the forge-formation process and the friction welding+thermomechanical treatment will be employed as themain method,and that the serial applied processes of the hollow sucker rod will be the effective selection by domestic exploitation of heavy oil field,high wax oil field and gas field.
