一种套管外螺纹清洗装置
本技术涉及螺纹清洗装置
,具体涉及一种套管外螺纹清洗装置。
技术介绍
套管是油气井的重要组成部分。单根套管一般长为10米,数百根套管通过螺纹连接在一起,从地面直达地下油气层,从而形成油气的运移通道,为油气的生产提供可能。套管螺纹是一种特殊的锥形密封螺纹,它的完整性及清洁性直接关系到钻完井作业的成败。由于套管从出厂到入井前多存放于露天的场地,并且存放时间较长,在这段时间内套管受风吹、雨打、日晒等因素影响,套管螺纹表面极易粘上赃物、硬质颗粒物等异物,若在连接螺纹时不清理掉这些异物,影响螺纹的密封性及连接强度等性能,给井下造成安全隐患。所以,在钻井准备阶段,清洗螺纹是最重要的准备工作之一,但目前套管螺纹的清洗方法还比较原始,主要是用钢丝刷和棉布手工擦拭,费时费力不说,效果还得不到保证。
