Abstract
本实用新型涉及一种井下作业工具，特别涉及一种井下作业泄油管柱，其技术方案是：包括接箍、垫圈、油管短节、外接头、挡座、剪断销钉、限位销、弹簧、伸缩短节，接箍连接油管短节，油管短节连接外接头，外接头通过挡座连接伸缩短节，限位销放置在伸缩短节的上面，挡座与伸缩短节由剪断销钉连接，挡座上面连接有弹簧，接箍内部设有垫圈；本实用新型的有益效果是：泄油管柱位于抽油泵的泵下与油管之间，上端螺纹连接抽油泵，下端与油管螺纹连接。泄油管柱与抽油泵、油管、筛管、油管、死堵连接后下入井底，通过泄油管柱在井内泄掉泵上及油管内的污油污水，防止起油管时将污油污水带到地面，减少环境污染，操作方便、安全，使用寿命长，泄污效果好。
Description
井下作业泄油管柱
技术领域
[0001] 本实用新型涉及一种井下作业工具，特别涉及一种井下作业泄油管柱。
背景技术
[0002] 油水井在采油、注水的过程中，因地层出砂、出盐，造成地层掩埋、泵砂卡、盐卡，油田管柱堵塞，使油水井不能正常生产，影响油田的产量，起油管时将污油污水带到地面，造成环境污染。
发明内容
[0003] 本实用新型的目的就是针对现有技术存在的上述缺陷，提供一种井下作业泄油管柱，减少环境污染，操作方便、安全。
[0004] 其技术方案是:包括接箍、垫圈、油管短节、外接头、挡座、剪断销钉、限位销、弹簧、伸缩短节，接箍连接油管短节，油管短节连接外接头，外接头通过挡座连接伸缩短节，限位销放置在伸缩短节的上面，挡座与伸缩短节由剪断销钉连接，挡座上面连接有弹簧，接箍内部设有垫圈。
[0005] 本实用新型的有益效果是:泄油管柱位于抽油泵的泵下与油管之间，上端螺纹连接抽油泵，下端与油管螺纹连接。泄油管柱与抽油泵、油管、筛管、油管、死堵连接后下入井底，通过泄油管柱在井内泄掉泵上及油管内的污油污水，防止起油管时将污油污水带到地面，减少环境污染，操作方便、安全，使用寿命长，泄污效果好。·附图说明
[0006] 附图1是本实用新型的结构示意图；
[0007] 上图中:接箍1、垫圈2、油管短节3、外接头4、挡座5、剪断销钉6、限位销7、弹簧8。
具体实施方式
[0008] 结合附图1，对本实用新型作进一步的描述:
[0009] 本实用新型包括接箍1、垫圈2、油管短节3、外接头4、挡座5、剪断销钉6、限位销
7、弹簧8、伸缩短节9，接箍I连接油管短节3，油管短节3连接外接头4，外接头4通过挡座5连接伸缩短节9，限位销7放置在伸缩短节9的上面，挡座5与伸缩短节9由剪断销钉6连接，挡座5上面连接有弹簧8，接箍I内部设有垫圈2。
[0010] 使用时，泄油管柱位于抽油泵的泵下与油管之间，上端螺纹连接抽油泵，下端与油管螺纹连接。泄油管柱与抽油泵、油管、筛管、油管、死堵连接后下入井底，通过泄油管柱在井内泄掉泵上及油管内的污油污水，防止起油管时将污油污水带到地面，减少环境污染，操作方便、安全，使用寿命长，泄污效果好。
