Abstract

本实用新型涉及磨鞋,包括主体、硬质合金,硬质合金镶嵌在主体头部,其特征在于,所述主体头部设有三只水眼,硬质合金上对应水眼设有豁口。所述水眼轴线与主体轴线夹角25~35°,直径13~20mm。与现有技术相比,本实用新型的有益效果是:1)硬质合金镶嵌在主体头部采用了先进的整体烧结工艺,大大延长了磨鞋的使用寿命;2)根据流体力学原理三只水眼倾斜分布,使液流的冲击形成了交变力场,有效净化了井底工作面,进一步增强了磨鞋的磨削效果。

Description

磨鞋
技术领域
本实用新型涉及修井工具领域,尤其涉及一种磨鞋。
背景技术
磨鞋是一种常见的修井工具,主要用来磨削井下落物以及其它不稳定落物,如钻井过程中遗留的螺栓、螺母、钻杆、牙轮等,因为磨鞋底面一般为凹面形状,因此特别方便磨削。生产中,将落物磨碎后,需向井下注水,将异物冲出,操作不方便。
发明内容
本实用新型的目的是提供一种磨鞋,磨削时,不用抽出磨鞋即可向井下注水,提高修井效率。
为解决上述技术问题,本实用新型的技术方案是:
磨鞋,包括主体、硬质合金,硬质合金镶嵌在主体头部,所述主体头部设有三只水眼,硬质合金上对应水眼设有豁口。所述水眼轴线与主体轴线夹角15~25°,直径13~20mm。
与现有技术相比,本实用新型的有益效果是:1)硬质合金镶嵌在主体头部采用了先进的整体烧结工艺,大大延长了磨鞋的使用寿命;2)根据流体力学原理三只水眼倾斜分布,使液流的冲击形成了交变力场,有效净化了井底工作面,进一步增强了磨鞋的磨削效果。
附图说明
图1是本实用新型实施例结构示意图;
图2是图1的侧视图。
图中:1-主体 2-硬质合金 3-水眼 4-豁口
具体实施方式
下面结合附图对本实用新型的具体实施方式作进一步说明:
见图1、图2,是本实用新型磨鞋实施例结构示意图,包括主体1、硬质合金2,硬质合金2镶嵌在主体1头部,主体1头部设有三只水眼3,硬质合金2上对应水眼3设有豁口4。水眼3轴线与主体1轴线夹角16°,直径15mm。

Claims (2)

1.磨鞋,包括主体、硬质合金,硬质合金镶嵌在主体头部,其特征在于,所述主体头部设有三只水眼,硬质合金上对应水眼设有豁口。
2.根据权利要求1所述的磨鞋,其特征在于,所述水眼轴线与主体轴线夹角15~25°,直径13~20mm。
