Abstract

一种油田井杆扶正器,扶正器为管状结构套筒,两端为弧形端面,扶正器表面轴向均匀分布有若干条支撑筋,扶正器内壁也可以镶嵌有定位环。由于采用了轴向支撑筋结构和自润滑增强尼龙塑料材质,扶正器套装在油田井杆上时,对井杆起到了支撑扶正作用,避免了井管、接箍与油管管壁直接摩擦,有效的保护了油管,延长了油管使用寿命,降低了维修费用。

Description

采油井杆扶正器
本实用新型涉及采油井井杆的保护装置,确切地讲是公开一种采油井井杆扶正器,属于采油机械设备技术领域。
采油设备中由于井杆长达8米及井杆接箍很重,所以在斜井采油过程中油井井杆、井杆接箍与油管的摩擦是不可避免的,井杆和井杆接箍为金属材质,严重的磨损油管,导致油管很快被磨漏,油井报废。
本实用新型公开一种采油井杆扶正器,任务是解决井杆、井杆接箍与油管的摩擦问题。
本实用新型的任务是这样完成的:扶正器为管状结构套筒,两端为弧形端面,扶正器表面轴向均匀分布有若干条支撑筋。扶正器内壁也可以镶嵌有定位环。
扶正器为具有自润滑功能的增强尼龙塑料制成,将其固定在井杆上或井杆接箍表面,通过其上的支撑筋与油管内壁接触,降低了摩擦系数,减少了油管的摩擦程度。
本实用新型的积极效果在于:由于采用了轴向支撑筋结构和自润滑增强尼龙塑料材质,扶正器套装在油田井杆上时,对井杆起到了支撑扶正作用,避免了井杆、井杆接箍与油管管壁直接摩擦,有效的保护了油管,延长了油管使用寿命,降低维修费用。
图1为本实用新型结构原理图。
图2为本实用新型剖面图。
下面结合附图进一步描述本实用新型:参照图1、2,尼龙塑料制成的扶正器为管状结构套筒1,两端为弧形端面,扶正器表面轴向均匀分布有若干条支撑筋2,在本实施例中为对称分布四条支撑筋,支撑筋2之间为导油通道,减少了原油的阻力。扶正器内壁也可以镶嵌有两个定位环3,通过固定环更牢固的将扶正器固定在井杆4上。

Claims (2)

1、一种油田井杆扶正器,其特征在于:扶正器为管状结构套筒(1),两端弧形端面,扶正器表面轴向均匀分布有若干条支撑筋(2)。
2、根据权利要求1所述的扶正器,其特征在于:扶正器内壁镶嵌有定位环(3)。
