CS-HI HYDRAULIC-SET RETRIEVABLE PACKER

INTRODUCTION

     CS-HI Packer is bi-directional slip retrievable hydraulic production packer released by straight pulling  the tubing string upward. The non-directional upper slip releasing system can reduce the upward  pulling force on the slip. Dislocating a key non-directional slip first triggers an automatic release of the  other slips .  CS-HI packer is recommended for use in well completions where the packer will be set after the  well has been flanged up, as well as in deviated wells, gas-lift wells, and other completions where a  mechanical-set packer is not suitable. The equalizing system of the packer can equalize the pressure  differential between upper and lower.

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.

Note: Other specification products are available.
