Heat-Resistant Packers PTK-2-140-350; PTK-118-350

The heat-resistant packers PTK-2-140-350 and PTK-118-350 have a distinctive feature due to the built-in adjustable temperature compensator. Due to this feature the thermally insulated tubing elongations are compensated for by temperature compensator traveling inside the packer, which significantly increases the reliability of the whole set of heat-resistant equipment.
The heat-resistant packers are designed to protect the casing from high temperature exposure and pressure during the steam injection as well as compensating for the thermal expansions of the thermally-insulated tubing. These packers are installed on the lower end of the thermally-insulated tubing.
The packer setting is carried out by rotating thermally-insulated tubing string at the intended depth of installation. Removal of the packer is carried out by moving the thermally-insulated tubing string upwards using the pulling tool.
