Description

单向卡瓦水力锚 
一、技术领域
本实用新型涉及一种油田采油用的管柱锚定装置,具体的讲是一种单向卡瓦水力锚。 
二、背景技术
在油田采油过程中,为防止井内压大,井内管柱向上串动,一般都将水力锚接在管柱上,当井内压力大时,井内的液体顶起水力锚的锚爪,使锚爪上的合金块锚定在套管壁上,防止管柱因井内压力大而向上串动。但现有的水力锚装置在实际运用中,由于其自身结构问题,极其容易造成卡管柱和不能及时回位的现象,给施工带来极大的不便。 
三、实用新型内容
本实用新型的目的就是针对现有技术存在的缺陷,提供一种结构简单、操作方便的单向卡瓦水力锚。 
其技术方案是:它包括中心管、锚爪,其特征在于:中心管顶端设有一锥体,锥体下端设有锚爪孔,中心管上设有锚爪,锚爪位于锚爪孔内部,中心管上设有弹簧,弹簧连接锚爪,中心管外壁设有滑动密封套,中心管下端设有接头。 
本实用新型结构简单,使用方便,且操作灵活,具有锚定牢靠、解锚可靠等优点。 
四、附图说明
附图是本实用新型一种实施例的结构示意图。 
五、具体实施方式
如图所示,一种单向卡瓦水力锚,包括中心管7、锚爪3,中心管7顶端设有一锥体1,锥体1下端设有锚爪孔2,中心管1上设有锚爪3,锚爪3位于锚爪孔2内部,中心管7上设有弹簧4,弹簧4连接锚爪3,中心管7外壁设有滑动密封套5,中心管7下端设有接头6。
