Abstract

一种复合打捞器,由三扣接头、滑块、矛杆、外筒、母锥组成,三扣接头下部小螺纹与矛杆上部联接,三扣接头下部大螺纹与外筒上部联接,外筒下部与母锥上部联接,矛杆上安装滑块,矛杆下端为圆锥形,母锥内有锥形螺纹。母锥内的锥形螺纹的锥度为1∶16,螺距为3.17mm。下部的母锥可以打捞油管接箍,滑块、矛杆可以对油管进行内捞,当油管断口不整齐时,可将油管引入矛杆与外筒之间,外筒约束劈开的油管不会向外张开,滑块捞住劈开的油管的内壁,从而将其打捞上来。因此,本实用新型除能打捞普通井下落物外,还能打捞断口不整齐的油管,适应范围广,修井成功率高。

Description

复合打捞器
技术领域:
本实用新型属油田油、水井作业打捞工具,是一种复合打捞器。
背景技术:
油水井生产和修井作业过程中,掉落了各种管具在井内,需要打捞后才能正常生产,目前打捞工具都是单一的,只能适合打捞特定形状的管具,当油管断口不整齐时,就不能打捞,因此,现有的打捞工具适应范围小。
发明内容:
本实用新型的目的是提供一种复合打捞器,使其能打捞断口不整齐的油管。
本实用新型的目的是这样实现的:由三扣接头、滑块、矛杆、外筒、母锥组成,三扣接头下部小螺纹与矛杆上部联接,三扣接头下部大螺纹与外筒上部联接,外筒下部与母锥上部联接,矛杆上安装滑块,矛杆下端为圆锥形,母锥内有锥形螺纹。
母锥内的锥形螺纹的锥度为1∶16,螺距为3.17mm。
本实用新型的有益效果是:除能打捞普通井下落物外,还能打捞断口不整齐的油管,适应范围广,修井成功率高。
附图说明:
附图是本实用新型实施例的安装图。
具体实施方式:
由三扣接头1、滑块2、矛杆3、外筒4、母锥5组成,三扣接头1下部小螺纹与矛杆3上部联接,三扣接头1下部大螺纹与外筒4上部联接,外筒4下部与母锥5上部联接,矛杆3上安装滑块2,矛杆3下端为圆锥形,母锥5内有锥形螺纹。母锥5内的锥形螺纹的锥度为1∶16,螺距为3.17mm,便开打捞造扣。下部的母锥5可以打捞油管接箍,滑块2、矛杆3可以对油管进行内捞,当油管断口不整齐时,可将油管引入矛杆3与外筒4之间,外筒4约束劈开的油管不会向外张开,滑块捞住劈开的油管的内壁,从而将其打捞上来。
