CS-HIP 封隔器液压坐封的隔离封隔器，主要用于注水。CS-HIP 封隔器采用液压推动串联的双级活塞压缩胶筒坐封，同时机械锁紧止退。需要洗井时，油套环空加压0.5MPa即可开启洗井阀，实现洗井功能。注水时，油管内压力高于套管压力，洗井阀关闭，各层间分隔，实现分层注水。直接上提管柱解封。

主要特性

◎ 操作简单，操作方便； 

◎ 液压坐封；

◎ 上提剪切解封； 

◎ 坐封过程中没有中心管柱运动，可以与其他封隔器组合使用；

◎ 封隔器性能可靠，稳定性高。

CS-HIP HYDRAULIC-SET RETRIEVABLE PACKER

INTRODUCTION

CS-HIP Packer is a hydraulic-set isolation packer mainly applied in water injection. This packer is set by means of pushing the series connected double pistons with hydraulic pressure to compress the element and meanwhile lock up mechanically for retaining. When well flushing is needed,  apply 2MPa pressure on annulus space of the tubing and casing to open the well flushing valve and realize the flushing function. In water injection operation, the tubing casing pressure differential closes the well flushing valve and separates different zones for zonal water injection.  Pull straight the string upward to release.

FEATURES

◎ Operationally easy; 

◎ Hydraulic set; 

◎ Pull straight upward and shear to release;  

◎ No mandrel movement during setting allows stacked packer applications; 

◎ Reliable performance;  

◎ Simple mechanism and reliable performance.

Note: Other specification products are available.
