Description

超大规格六方钻杆
技术领域
本实用新型涉及一种石油钻具,具体为一种超大规格六方钻杆。 
背景技术
目前油田采油,国外常用的最大规格是133.4六方钻杆,国内常用的最大规格是133.4四方钻杆,来做驱动钻杆传递扭矩;美国API标准中最大规格的四方钻杆是133.4mm,最大规格的六方钻杆是152.4mm,现在钻井规格逐渐增大,钻具规格也随之递增,为了适应市场需求,我们急需设计一种超出已有标准的超大规格六方钻杆。 
发明内容
本实用新型为了解决现有钻杆无法满足新形势下钻井规格要求的问题,提供了一种超大规格六方钻杆。 
本实用新型的技术方案,一种超大规格六方钻杆,结构包括六边形的驱动部分以及两端连接的上端接头、下端接头;全长12.5米,其中驱动部分长12米,驱动部分对边的宽是212mm,内径170mm,上端接头、下端接头长度是220mm,外径是250mm,上下端接头内分别采用左旋和右旋内螺纹。 
本实用新型的驱动部分对边直径是212mm,超出了美国API标准范围,该钻杆填补了石油钻具行业的空白;适用于大型号钻机钻大口径井,起驱动传递扭矩作用,这种大规格的方钻杆传递扭矩力是133.4方钻杆的2倍多,设计170mm大内径,更便于下探测仪器,远远超越了API标准中82.6mm的内径,采用特殊规格的双母螺纹设计,提高了方钻杆的使用寿命。 
附图说明
图1为本实用新型结构示意图 
图中: 1-上端接头,2-驱动部分,3-下端接头,4-反扣标记槽。
具体实施方式
如图1所示意,一种超大规格六方钻杆,结构包括六边形的驱动部分2以及两端连接的上端接头1、下端接头3;全长a为12.5米,其中驱动部分2长12米,驱动部分2对边的宽c是212mm,内径d为170mm,上端接头、下端接头长度b、e均是220mm,外径是250mm,上下端接头内分别采用左旋和右旋内螺纹。
