To expand the temperature range of the liner tube, our company has upgraded and developed POK high-temperature modified materials, with a Vicat softening temperature above 200°C and a long-term service temperature of up to 120°C. This effectively solves the problems of material hydrolysis, severe wear, and corrosion of the oil pipe under high temperatures, while reducing scaling and slowing down wax deposition. It is suitable for use in ultra-deep wells, high-temperature wells, wells with high acidity and alkalinity, and wells with high mineralization.
