Abstract

本实用新型涉及一种油田采油用的抽油杆，具体地讲是一种镦锻式接箍连接高抗扭矩空心抽油杆。其技术方案是：它包括杆体，杆体的一端设有镦锻式高抗扭矩公接头，杆体的另一端设有单体式高抗扭矩接箍，镦锻式高抗扭矩公接头外壁套装有耐高温密封圈。本实用新型克服了摩擦焊口处应力集中，容易断裂的情况，给采油效率的提高提供了可靠保障；其抗扭能力大大增强，可承受更高负荷的抗扭力；延长了空心抽油杆的使用寿命，降低采油成本。

Description

镦锻式接箍连接高抗扭矩空心抽油杆
一、技术领域
本实用新型涉及一种油田采油用的抽油杆，具体的讲是一种镦锻式接箍连接高抗扭矩空心抽油杆。
二、背景技术
目前，国内油田采油用的空心抽油杆多为摩擦焊式普通平扣空心杆，因其在使用时，存在最主要的两个弊病：一、两端螺纹容易卡住，且螺纹容易磕碰损伤，经常出现解不开接头的情况，给修井工带来很大的劳动强度，卡的较紧时，只能采用锯断的方法，因导致了空心抽油杆报废较多；二、接头及接箍跟杆体为摩擦焊接式，经常出现因摩擦焊口应力集中而发生裂纹、断脱的现象，给采油作业带来了很大的困难，给油田造成了很大的经济损失。
三、实用新型内容
本实用新型的目的就是针对现有技术存在的缺陷，提供一种结构简单、成本低廉的镦锻式接箍连接高抗扭矩空心抽油杆。
其技术方案是：它包括杆体，杆体的一端设有镦锻式高抗扭矩公接头，杆体的另一端设有单体式高抗扭矩接箍，镦锻式高抗扭矩公接头外壁套装有耐高温密封圈。
本实用新型克服了摩擦焊口处应力集中，容易断裂的情况，给采油效率的提高提供了可靠保障；其抗扭能力大大增强，可承受更高负荷的抗扭力；延长了空心抽油杆的使用寿命，降低采油成本。
四、附图说明
附图是本实用新型一种实施例的结构示意图。
五、具体实施方式
如图所示，一种镦锻式接箍连接高抗扭矩空心抽油杆，包括杆体3，杆体的3一端设有镦锻式高抗扭矩公接头1，杆体3的另一端设有单体式高抗扭矩接箍4，镦锻式高抗扭矩公接头1外壁套装有耐高温密封圈2。
