ISOLATION PACKER

INTRODUCTION

Isolation packer is mainly used in heavy oil thermal recovery well cyclic steam stimulation, displacement, SAGD process with packer for thermal injection as well. The packer is designed between the reservoir unit to realize the reservoir unit seal, separate the high permeability layer and low permeability layer effectively. Therefore, the packer can prevent interference of the injected fluid and guarantee the accuracy of the each unit injection quantity. The packer uses thermal agents as the power source of the elastomeric element. When the temperature rises, thermal reagent volume will swell, pushing the piston to set the elastomeric element.

FEATURES

◎ Temperature rating 350℃ , pressure rating 20MPa;

◎ Using lock configuration to maintain sealing effect of packer considering temperature changes;

◎ Thermal set and released by lifting the string.

Note: Other specification products are available.
