大庆油田深层气井连续油管输送桥塞技术应用

Application of Coiled Tubing Bridge Plug Technology to Deep Gas Well in Daqing Oilfield

深层气井套管压裂后,采用连续油管输送桥塞工艺,实现对井筒安全、快速的封堵,解决了油管输送桥塞施工时间长、完井液消耗大、施工风险高的问题。阐述了连续油管输送桥塞的技术特点及工艺原理,通过现场应用,证明该工艺是深层气井压后快速封堵储层行之有效的方法。

Coiled tubing transporting bridge plug technology is used after fracturing to deep gas well,which can realize block implementation of wellbore safety and fast,solve the problems of long operation time of delivery bridge plug,big cost of completion fluid,high risk of construction. The technique characteristics and principle of the coiled tubing transporting bridge plug are illustrated,and through field application,it is proved that the process is an effective method to rapidly seal for the deep gas well reservoir after fracturing.
