CS-HG6 封隔器是一款双向卡瓦、可回收式单管封隔器，用于注水和者提高采 收率等浅层井。由于这些井较浅，封隔器设计允许在拉伸或压缩状态下坐封。双向卡 瓦可以允许油管选择处于拉伸、压缩状态，封隔器也适合与诸如On-Off工具、井下 关断阀以及其他相关的完井工具配合使用。

主要特性

◎ 结构紧凑，工具体积较小，方便运输和下入； 

◎ 内部旁通为工具下井、解封和取出增加可靠性； 

◎ 创新的密封系统增强了工具承压能力； 

◎ 双向卡瓦允许封隔器承受来自上下两个方向的压力；

◎ 紧急剪切解封功能； 

◎ 低成本。

CS-HG6  MECHANICAL RETRIEVABLE PACKER

INTRODUCTION

CS-HG6 packer is a double-grip, retrievable, single string packer designed for service in waterflooding and enhanced oil recovery. Because many of these wells are shallow, the packer was  designed to allow the packing elements to be packed off with either tubing tension or compression at  the packer. The double-grip feature allows the option of leaving tubing in compression or tension and  makes the packer suitable for use with accessories such as on-off tools, downhole shut-off valves, and  other related completion tools.

FEATURES

◎ Short compact length;

◎ Compatible with plastic coating, sour service trim, or special flow wet metallurgy; 

◎ Internal bypass valve provides reliable running, releasing, and retrieving; 

◎ Innovative packing element system for positive pressure-enhanced pack-off; 

◎ Opposing slip design holds forces from either direction while loaded slip remains on the low  pressure side of the tool; 

◎ Emergency shear release; 

◎ Take-up feature allows pressure differential to increase and lock in added rubber compression.

Note: Other specification products are available.
