多功能安全接头的研制与应用

Development and Application on the Multifunction Safety Connector

水井分注、卡封作业时普遍存在管柱试压不达标,下次检封仍不能起出全部管柱的问题。针对这些问题研制了多功能安全接头,介绍了该工具的结构、工作原理及现场使用情况。

When the whole layered water injection strings have been run into the hole, the pressure test for the tubing strings often can not meet the requirement of the standards, and when the next packer-check operation is conducted, the whole tubing strings can not be pulled out of the hole while we try our best to do it. For resolving the problems above, the multifunction safety connector has been developed and manufactured. The structure, working principle and field application of the device are introduced in this article.
