Product Features
1. The acid fracturing thickening agent is mainly used in the development of carbonate reservoirs. Due to the development of pores and fractures in carbonate reservoirs and the high formation temperature, it is necessary to increase the penetration depth of acid fracturing fractures in reservoirs and improve the conductivity of acid-corroded fractures to ensure the effect of acid fracturing transformation. Therefore, adding thickening agent into the acid fracturing system can delay the reaction speed between acid liquor and formation rocks, improve the sweep coefficient, enhance the sand carrying capacity, reduce filtration, and ultimately achieve the purpose of increasing production and injection.
2. This product has good thermal stability and shear rheology, good filtration reduction and excellent compatibility. It is well compatible with most corrosion inhibitors, demulsifiers, ferric ion stabilizers, anti-swelling agents, etc., and easily soluble in water and acids. At the same time, the viscosity of acid liquor is high, which effectively reduces the reaction speed between acid and carbonate rock formation, increases the treatment radius of acid liquor, improves the acidizing effect and enhances the oil recovery efficiency.
