Abstract

一种防腐蚀抽油杆,包括抽油杆,所述的抽油杆表层进行QPQ盐浴处理,形成QPQ盐浴层,采用本技术方案,抽油杆表层形成一层耐腐蚀的表层,使抽油杆具有超强的耐腐蚀性,使用过程中,井液虽然与抽油杆接触,但经过QPQ盐浴处理后的抽油杆具有超强的耐腐性,抽油杆不会被腐蚀,可以增加抽油杆的使用寿命。

Description

一种防腐蚀抽油杆
技术领域
本实用新型涉及油田机械设备领域,尤其涉及一种抽油杆,具体是指一种防腐蚀抽油杆。
背景技术
在油田抽油系统中,抽油杆浸泡在井液中工作,井液中含有腐蚀性介质,对抽油杆产生腐蚀,造成抽油杆柱的使用寿命短,油井生产周期短,经济效益差。为了解决这一问题,油田使用过材料型防腐蚀性抽油杆,但这种抽油杆是金属材料,抗腐蚀能力有限,不能完全解决被腐蚀的问题。
发明内容
本实用新型要解决的技术问题是针对现有技术所存在的不足之处,提供一种耐腐蚀性强、使用寿命长的一种防腐蚀抽油杆。
本实用新型的技术解决方案是,提供如下一种防腐蚀抽油杆,包括抽油杆,所述的抽油杆表层进行QPQ盐浴处理,形成QPQ盐浴层。
本实用新型的有益效果是:采用本技术方案,抽油杆表层进行QPQ盐浴处理,形成QPQ盐浴层,运用QPQ盐浴复合处理技术,形成一层耐腐蚀的表层,使抽油杆具有超强的耐腐性,增加了抽油杆的使用寿命。
附图说明
附图是本实用新型的装配图。
图中所示:1、抽油杆,2、盐浴层。
具体实施方式
为便于说明,下面结合附图对本实用新型的防腐蚀抽油杆做详细说明。如附图中所示,一种防腐蚀抽油杆,包括抽油杆1,所述的抽油杆1表层进行QPQ盐浴处理,形成QPQ盐浴层2。使用过程中,井液虽然与抽油杆1接触,但经过QPQ盐浴处理后的抽油杆1具有超强的耐腐性,因此,抽油杆1不会被腐蚀。
