CS- FH封隔器是一种单管柱、液压坐封、可回收封隔器。CS- FH封隔 器通过投入堵塞器、油管打压来实现液压坐封。封隔器直接上提即可解封。 CS-FH封隔器适用于生产、注水和分层隔离，广泛应用于机械坐封式封隔器不 适用的大斜度井或水平井。

主要特性

◎ 操作简单，便于现场应用；

◎ 坐封及解封力可调节；

◎ 内置卸载器和旁通，辅助解封和回收；

◎ 液压内锁系统防止提前坐封；

◎ 三片不同硬度的胶筒组合，适用于多种不同规格套管；

◎ 双向卡瓦, 短而紧凑的设计，能够承受来自两个方向的压差；

◎ 坐封过程中没有中心管柱运动，适于组合使用。

CS-FH HYDRAULIC-SET RETERIVABLE PACKER

INTRODUCTION

CS-FH Packer is hydrostatic set and shear release single string retrievable packer. The CS-FH Packer  is hydraulically activated by applying tubing pressure against a plugging device below the packer.  The packer requires only straight pull to release. The CS-FH Packer is applied for production, injection  and zonal isolation and is especially suitable for highly deviated or horizontal wells where mechanical  setting packer are not applicable.

FEATURES

◎ Operationally simple; 

◎ Field adjustable shear release; 

◎ Built-in unloader and bypass – to aid in releasing and retrieving;  

◎ Pack-off is mechanically locked and constantly reinforced by hydrostatic pressure; 

◎ Triple seal multi-durometer elements- insure pressure integrity over a wide range of Temperatures  and conforms easily to casing irregularities; 

◎ Bi-directionally anchored, able to withstand pressure differential from two directions;

◎ No mandrel movement during setting allows stacked packer applications.
