Product Overview

The high-temperature salt-tolerant corrosion inhibitor is specifically developed for acidizing treatment of high-temperature, high-salt oil, gas, and water wells with reservoir temperatures ranging from 120 to 150 °C. Its multiple polar groups strongly adsorb onto the metal surface and undergo complexation reactions, forming a dense multi-molecular complex adsorption film. It provides corrosion inhibition by suppressing cathodic processes and, to a certain extent, also through control of anodic processes. This product exhibits good solubility in acid, excellent stability, a low freezing point, and significant high-temperature corrosion inhibition performance.
