HANGING PACKER

INTRODUCTION

The hanging packer is used in CSS and water shutoff operation in thermal recovery wells. It can seal the annulus preventing the steam from getting to the annulus above the packer. Besides, the packer can hang firmly in the wellbore so it can also be used for hanging or supporting the anti-pollution string.

FEATURES

◎ Dual sealing design, sealing reliable;

◎ Temperature rating 350℃ , working pressure rating 20MPa;

◎ Sealing performance independent of temperature change on alternate;

◎ With release function;

◎ Reliable long-term sealing performance at high temperature;

◎ Anti-pollution string can be formed when the tool incorporating with underground switch;

◎ Can be used as a bridge plug for thermal recovery.

BENEFITS

◎ Good performance of high-pressure and high-temperature;

◎ With reliable performance of sealing, anchoring and releasing;

◎ Can be placed in the well for long-term;

◎ Sealing performance is unaffected by temperature alternately changes.
