Abstract

本实用新型属于钻井设备技术领域,公开了一种带有加厚段的耐磨钻铤,其包括管体、公接头、母接头,管体中部设有外凸的加厚段,加厚段及母接头的外边设有陶瓷涂层。作业时加厚段可防止井壁对管体磨损,加厚段及母接头外表的陶瓷涂层增加了钻铤易损部件的耐磨、耐腐蚀强度,延长了钻铤整体的使用寿命。

Description

带有加厚段的耐磨钻铤
技术领域
本实用新型涉及一种钻铤,属于钻机技术领域,具体为一种带有加厚段的耐磨钻铤。
背景技术
在石油、天然气、水源和矿藏的钻探过程中,都需要用到钻铤。钻铤的结构虽然简单,但是其要达到的质量要求却比较高。通常的钻铤在钻探的过程中,受到的冲击较大,钻铤容易受到震动而损坏;并且钻井中的淤泥常含有腐蚀性,会对钻铤表层及接头处进行腐蚀,长期以往会导致钻铤工作不正常,甚至引发安全事故。
实用新型内容
为克服上述技术问题,本实用新型提供了一种耐磨、耐腐蚀使用寿命长的带有加厚段的耐磨钻铤。
为实现上述技术目的,本实用新型是采用以下技术方案实现的:一种带有加厚段的耐磨钻铤,包括管体、公接头、母接头,其特征在于:管体中部设有外凸的加厚段,加厚段及母接头的外边设有陶瓷涂层。
本实用新型的有益效果是:管体中部设有加厚段,增加了钻铤的强度,减少了钻铤钻探时管体受到的震动,作业时加厚段可防止井壁对管体磨损,加厚段及母接头外表的陶瓷涂层增加了钻铤易损部件的耐磨、耐腐蚀强度,延长了钻铤整体的使用寿命。
附图说明
附图为本实用新型的结构示意图。
图中,1、公接头,2、加厚段,3、管体,4、母接头。
具体实施方式
参看附图,一种带有加厚段的耐磨钻铤,包括管体3、公接头1、母接头4,其特征在于:管体3中部设有外凸的加厚段2,加厚段2及母接头4的外边设有陶瓷涂层。
