Product Introduction
The main component of this product is cationic polymer, mainly used for thickening in oil and gas well acidizing operations. The product has the following advantages: simple on-site preparation, low dosage, good temperature and shear resistance, and good thickening effect even with small dosage. This product is a cationic polymer, which also has the effect of preventing clay expansion and particle migration. It has good drainage performance and good compatibility with other additives used in acid liquids (such as corrosion inhibitors, iron ion stabilizers, drainage aids, etc.).
