可捞式油管堵塞器设计与应用

Design and Application of Fishable Tubing Plug

在注水井带压作业工艺中,由于常规的油管堵塞器不可打捞,无法进行其他作业。因此,研制了可捞式油管堵塞器。介绍了该堵塞器的结构、工作原理。该可捞式油管堵塞器结构简单、制造成本低,可代替常规油管堵塞器使用,同时又可避免常规油管堵塞器不可打捞而导致的作业复杂化问题。

During the water injection well under pressure operation,the conventional tubing plug can＇t be fishable so that the sequent jobs cannot be continued. Therefore the fishable tubing plug is studied to solve the problem. The article introduces the structure and operational principle of tbe type of tubing plug. The fishable tubing plug has the advantages of simple structure,low cost, and can be used to replace the conventional tubing plug,and meanwhile it can avoid complex jobs wbich were caused by the irretrievable conventional tubing plug.
