一趟管柱套管外串封固工具研制

The Development of Thimble Outwards Oustering Sealing-up Facility-One String Trip.

套管外串封固工具一趟管柱能实现丢手坐封、封堵挤注串槽,避免灰浆反吐、阻止挤注段亏空,减少了作业工序,缩短了施工周期。经现场应用,效果良好。

Thimble outwards clustering sealing-up facility-one string trip can realize releasing setting, plug squeezing infuse clustering launder; avoid mortar's regurgitation,prevent deficit of squeezing infuse mbr,reduce test working procedure,shorten test period. It has been proved very usefully in field.
