Abstract

本实用新型涉及一种柱形磨鞋,磨鞋主体和铣刃,磨鞋主体顶端与钻柱采用螺纹连接,磨鞋主体表面设有螺旋状铣刃。本实用新型结构简单,操作方便,可广泛用于管状物体的修整。

Description

柱形磨鞋
技术领域
本实用新型涉及一种修整工具,特别是涉及一种柱形磨鞋。
背景技术
柱形磨鞋用来修整略有弯曲或轻度变形的套管、修整下衬管时遇阻的井段和用以修整错位不大的套管断脱井段,套管断口错位不大于40mm。目前使用的磨鞋工具结构不完善,操作不方便,极大的影响了工作效率。
发明内容
本实用新型克服了现有技术中的不足,提供了一种结构设计合理,操作方便的柱形磨鞋。
为了解决上述问题,本实用新型采用以下技术方案:
柱形磨鞋,磨鞋主体和铣刃,磨鞋主体顶端与钻柱采用螺纹连接,磨鞋主体表面设有螺旋状铣刃。
所述的磨鞋主体内部中心处为柱形空腔结构。
与现有技术相比,本实用新型的有益效果是:
本实用新型结构简单,操作方便,修整效果好,有效的提高了工作效率和工作质量。
附图说明
图1为本实用新型结构示意图。
具体实施方式
柱形磨鞋,如图1所示,磨鞋主体1和铣刃2,磨鞋主体1顶端与钻柱采用螺纹连接,磨鞋主体1表面设有螺旋状铣刃2,磨鞋主体1内部中心处为柱形空腔结构。
当套管变形后其它工具管柱不能顺利通过时,可采用柱形磨鞋磨铣,柱形磨鞋是从套管径向方向磨削,可以增加套管的直度,柱形磨鞋的外径尺寸均相同,长度可随需要变化,以达到逐步修直的目的。

Claims (2)

1.柱形磨鞋,其特征在于,磨鞋主体和铣刃,磨鞋主体顶端与钻柱采用螺纹连接,磨鞋主体表面设有螺旋状铣刃。
2.根据权利要求1所述的柱形磨鞋,其特征在于,所述的磨鞋主体内部中心处为柱形空腔结构。
