Abstract

校深防碰接头,涉及油田射孔测试联作领域,校深时测试管柱中断销循环阀的保护,包括本体,本体的上端设置外螺纹,外螺纹下方的本体外周均布四个扶正块,本体中部设有中心孔。使用时将校深防碰接头连接在自然咖吗磁定位校深仪的下部,因其外径比油管内径小,比测试管柱中断销式反循环阀的内径大,因此确保了校深时自然咖吗磁定位校深仪下入油管后不能碰撞到断销式反循环阀,提高了施工的安全。

Description

校深防碰接头
技术领域
本实用新型涉及油田射孔测试联作领域,校深时测试管柱中断销循环阀的保护。
背景技术
射孔测试联作工艺,一趟管柱完成射孔测试、抽汲作业三项工作,它安全、高率和能缩短试油周期,在各油田广泛使用,但较深时有时受深度仪误差、电缆自然伸长和人为因素影响,自然咖吗磁定位校深仪有时容易碰断测试管柱中的断销式反循环阀内的断销而导致管柱漏失和测试返工。2009年在庄3井和邵深1井先后就发生上述问题,影响了施工周期和测试成功率。
发明内容
本实用新型的目的是为了克服现有技术的不足,提供一种自然咖吗磁定位校深时测试管柱中断销式反循环阀的防碰撞工具,确保了测试成功。
本实用新型的目的是这样实现的:校深防碰接头,包括本体,本体的上端设置外螺纹,外螺纹下方的本体外周均布四个扶正块,本体中部设有中心孔。
使用时将校深防碰接头连接在自然咖吗磁定位校深仪的下部,因其外径比油管内径小,比测试管柱中断销式反循环阀的内径大,因此确保了校深时自然咖吗磁定位校深仪下入油管后不能碰撞到断销式反循环阀,提高了施工的安全。
附图说明
图1为本实用新型的一种结构示意图。
图2为图1的俯视图。
具体实施方式
如图1、2所示,为校深防碰接头,包括本体2,本体2的上端设置外螺纹1,外螺纹1下方的本体2外周均布四个扶正块3,本体2中部设有中心孔4。
