Abstract

本实用新型公开了一种抽油杆井口保护器,它由主体、压帽和尼龙扶正体组成,压帽的两端设计成圆弧状,主体和压帽螺纹连接,在主体和压帽之间嵌有尼龙扶正体。该装置结构简单,设计合理,可起到充分保护杆体的作用,减少由于杆体损伤造成使用寿命缩短的情况。

Description

抽油杆井口保护器
本实用新型涉及一种抽油杆井口保护装置,属采油配套工具。
目前井下作业过程中,在起下抽油杆过程中,抽油杆与井口的起下工具接触,并发生摩擦、撞击等作用,造成抽油杆体的擦伤,涂层的剥落,使抽油杆局部损伤,从而缩短了使用寿命。
本实用新型的目的就是提供一种抽油杆井口保护器,它能避免抽油杆在下入过程中受到损伤。
本实用新型的目的是这样实现的:抽油杆井口保护器由主体、压帽和尼龙扶正体组成,压帽的两端设计成圆弧状,主体和压帽螺纹连接,在主体和压帽之间嵌有尼龙扶正体。
本实有新型具有结构简单,设计合理,能充分保护杆体,减少由于杆体损伤造成寿命缩短等优点。
下面结合附图对本实用新型做进一步描述:
图1:抽油杆井口保护器结构示意图;
图中:1-主体、2-压帽、3-尼龙扶正体;
如图1所示,抽油杆井口保护器由主体1、压帽2和尼龙扶正体3组成,主体1和压帽2通过丝扣联结并将尼龙扶正体3固定在中间。扶正体3的内径略小于主体1和压帽2的内径,使抽油杆始终保持居中不与周围的刚体接触,压帽2的两端设计成圆弧状,避免了起下过程中棱角对杆体的碰撞和刮削作用,即使力矩作用于杆体使其与刚体接触也不会被棱角划伤。
使用时将井口保护器与油管悬挂器联结(或用短节与悬挂器联结,或与上法兰盖联结),起下抽油杆时使其通过保护器即可起到保护作用。作业时抽油杆吊卡可座于保护器的压帽上,不影响正常的起下操作,但不能通过大直径的工具,如抽油杆扶正器等。由于保护器使抽油杆保持居中,并且起下时杆体与尼龙扶正体接触,两端的圆弧结构可以使杆体和接箍顺利通过,减少杆体的震动。
