Partially Hydrolyzed Polyacrylamide (PHPA) is a high-performance water-soluble polymer widely used in oilfield applications, enhanced oil recovery operations, and industrial water treatment processes. As a specialized form of anionic polyacrylamide, PHPA exhibits exceptional viscosity properties and shear stability, making it ideal for drilling fluids, fracturing fluids, and oilfield stimulation treatments. Its unique molecular structure provides superior performance in challenging operational conditions.
PHPA demonstrates outstanding performance in enhanced oil recovery (EOR) operations, where it improves sweep efficiency and increases oil production. It is also extensively used in waterflooding and polymer flooding applications to reduce water mobility and improve hydrocarbon recovery. The product exhibits excellent stability in saline and high-temperature environments, ensuring reliable performance in the most demanding oilfield conditions.
Our Partially Hydrolyzed Polyacrylamide is manufactured using advanced polymerization technology and undergoes rigorous quality testing to meet oilfield industry standards. We offer various molecular weight and hydrolysis degree options to suit specific reservoir conditions and operational requirements. Our technical team provides comprehensive support for product selection and field optimization.
Being anionic in nature, PHPA molecules attach to the positively charged edges of clay platelets, effectively binding them together. This encapsulation mechanism prevents cuttings from dispersing, making solids removal more efficient. Additionally, it forms a protective layer that slows water penetration into the shale, preventing swelling and erosion.
Technical Note: PHPA is highly stable but high temperature or high pH (>10.5) conditions should be monitored, as they can accelerate polymer hydrolysis and release ammonia traces. It should be added regularly while drilling shale sections to maintain consistent protective concentration.
