Abstract

本实用新型涉及一种钻柱用井壁刮削器，其与钻柱连接在一起，随钻柱的转动而一起转动。本实用新型采用的技术方案为：井壁刮削器主体是一个中空的圆柱体，上下两端均有用于连结的螺纹，单翼螺旋体是一个在圆柱体上的旋转120°的单翼螺旋体，PDC片是镶装在单翼螺旋体上组合而成。

Description

一种井壁刮削器
一、技术领域：
本实用新型涉及一种钻井井眼用井壁刮削器，为一种能接在井下钻柱中，防止正常钻进过程中钻头在井下时间过长，而起不出钻柱的井壁刮削器。
二、背景技术：
目前，国内外没有用于钻进过程中，保证井眼畅通的井壁刮削器，以及并壁刮削器类似的工作方法和原理。现有钻柱中没有接类似的切削和刮削工具，为保证钻柱能顺利被起出，在钻进过程中每隔一段时间就上提下放一次，以保证井眼畅通。
三、实用新型内容：
本实用新型为了解决上述背景技术中的不足之处，提供一种钻进用井壁刮削器，其与钻柱相接成为钻柱中的一部分，钻进过程中，随钻柱转动而重复刮削钻头刮削过的井壁，保持井眼畅通。
为实现上述目的，本实用新型采用的技术方案为：
一种钻柱用井壁刮削器，其特征在于：井壁刮削器与钻进中的钻柱中间连结在一起，成为钻柱中的一个组成部分，每个钻柱中可间断接入2-3个。
上述井壁刮削器由在圆柱主体上加工出一个单翼120°的螺旋体，与钻头直径一致，并在螺旋体上镶装保径齿，以及镶装能切削地层的PDC片，形成在一个圆柱体上有一个镶装刮削地层PDC片的单翼螺旋体组合而成。
与现有技术相比，本实用新型具有的优点和效果如下：
上述井壁刮削器由圆柱体上有一个镶装刮削地层PDC片的单翼螺旋体组合而成，接在钻井中的钻柱之中，与钻头直径一致，刮削井眼内壁，并使岩屑及时返出井眼和清除井眼中的固相颗粒，使其并径保持不变，中途不会因钻进时间过长而采用中途起下钻拉井壁。
四、附图说明：
图1为本实用新型的结构剖面图；
图2为本实用新型的工作状态参考图。
图中，1-井壁刮削器主体，2-单翼螺旋体，3-PDC片。
五、具体实施方式：
参见图1，本实用新型由井壁刮削器主体1、单翼螺旋体2、PDC片3组成，井壁刮削器主体1是一个中空的圆柱体，上下两端均有用于连结的螺纹，单翼螺旋体2是一个在圆柱体上的单翼螺旋体旋转120°，与钻头直径一致，PDC片3是镶装在单翼螺旋体2上。当井壁刮削器与钻柱连结在一起时，钻柱转动带动井壁刮削器一起转动，从而达到刮削井壁的作用，保持井壁干净和井眼直径不变。
如图2所示，当井壁刮削器与钻柱连结在一起后，随着钻柱的转动井壁刮削器也转动起来刮削井壁，保持井眼畅通。
