CS-RH 封隔器是一款液压坐封、双向锚定的可回收式封隔器。该封隔器为上部水力锚、下部卡瓦结构，当封隔器下部压力高于上部压力时，水力锚在液压力作用下伸出锚定在套管上。封隔器通过打压坐封，坐封后内部止退机构将封隔器锁定在坐封状态。解封时，直 接上提管柱，剪断封隔器的解封销钉，释放封隔器卡瓦及胶筒。

主要特性

◎ 能承受上下双向压差；

◎ 适用于中高压场合；

◎ 结构简单，易于操作，确保可靠性；

◎ 三片不同硬度的胶筒组合，胶筒防肩突设计；

◎ 内部旁通减小下入或取出时的抽汲效应；

◎ 活塞位于水力锚和卡瓦之间，坐封时没有 中心管移动；

◎ 直接上提剪切解封。

CS-RH HYDRAULIC-SET RETRIEVABLE PACKER

INTRODUCTION

The hydraulic-set CS-RH packer is a hydraulic-set bi-directional-anchored retrievable packer designed with upper anchor and lower slip structure. When the lower pressure of the packer is higher than the upper pressure, the hydraulic anchor will stretch out to the casing under the hydraulic pressure .The packer is set by pressuring up and then locked at the setting state with internal retaining structure. Pull straight upward on the tubing string and shear to cut the release screw to release the packer and element.

FEATURES

◎ PRotation operation is not necessary;

◎ Can withstand bi-directional pressure differential;

◎ Can be applied in medium to high pressure situations;

◎ Simple mechanism and easy operation ensure the reliability;

◎ Triple-seal multi-durometer elements with anti-shoulder projection design, internal by-pass design to decrease the swab effect when running or pulling;

◎ The piston is between the hydraulic anchor and slip, no mandrel movement when setting;

◎ Pull straight upward and shear to release.

Note: Other specification products are available.
