Performance: This product can be miscible with water in any proportion, remains stable under alkaline conditions, and exhibits excellent scale and corrosion inhibition below 200°C. It can chelate with various metal ions to form stable complexes. In aqueous solution, it undergoes multistage ionization to release H?, slowly dissolving carbonates. It can be used as a deep acidizing and blockage removal agent for acidification in oil and water wells, preventing the formation of CaF?, Fe(OH)?, and other precipitates in residual acid, thereby reducing secondary contamination of the oil layer during acidification operations.
