Heat-Resistant Packer PTK-3K-140-350
This packer is designed to seal the steam injection tubing lower end in 168 mm casing (OD) in oil-wells with large curvature sections in order to protect casing string from the effects of high pressure and temperature associated with the steam injection process.
This packer will also help reduce the heat loss along the wellbore in oilfields developed through thermal methods. It is designed for conditions with thermophore to a temperature up to 350 0C and a wellhead pressure up to 16 MPa.
