Description

地质摩擦钻杆
技术领域
本实用新型涉及一种钻杆,具体涉及一种地质摩擦钻杆。
背景技术
钻杆是用于水文地质勘探、水井及石油钻探设备等的常用机具。在生产实践中,普通地质钻杆在深孔钻进时,容易偏离直线,而且存在加工难度大,加工精度难以保证的缺陷。
实用新型内容
本实用新型的目的在于克服上述现有技术的不足,提供一种结构简单、使用寿命长,能够保证深孔钻进时对直线度要求的地质摩擦钻杆。
一种地质摩擦钻杆,包括钻杆本体,所述钻杆本体前部焊接有母接头,后部焊接有公接头;所述母接头、钻杆本体、公接头轴向方向开设有相通的通水孔,所述母接头、公接头与钻杆本体的焊接点均呈燕尾形。
本实用新型结构简单、抗弯强度高,焊接牢固,使钻杆的使用寿命大为增加,降低了使用成本。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
以下结合具体实施例,对本发明做进一步说明。应理解,以下实施例仅用于说明本发明而非用于限制本发明的范围。
实施例1
本实用新型提供的一种地质摩擦钻杆,包括钻杆本体1,所述钻杆本体1前部焊接有母接头2,后部焊接有公接头3,所述母接头2、钻杆本体1、公接头3轴向方向开设有相通的通水孔4,所述母接头2、公接头3与钻杆本体1的焊接点5处均呈燕尾形。
