分段封隔密封器主要用于稠油热采水平井水平段分段封隔注热，将水平段分隔成几个相对独立的注汽单元，每个单元能够分别进行独立的注汽，防止段与段间干扰。配合均衡注热阀使用，实现热采水平井水平段的分段封隔均衡注汽，提高水平井的注汽效果和油藏的动用程度。

主要特性

◎ 可双向承压；

◎ 多组热敏金属片均匀排列，胶筒径向受力均匀；

◎ 坐封温度200℃；

◎ 冷却后自行解封；

◎ 设计简单、紧凑。

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.
