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.
