Oilfield Chemicals
Partially Hydrolyzed Polyacrylamide (PHPA)
Partially hydrolyzed polyacrylamide (PHPA) features an ultra-high relative molecular mass, which endows the polymer with a large hydrodynamic molecular volume.
Product Features
- Partially hydrolyzed polyacrylamide (PHPA) features an ultra-high relative molecular mass, which endows the polymer with a large hydrodynamic molecular volume. Its aqueous solution delivers high initial viscosity and residual viscosity, effectively improving the temperature and salt resistance of the polymer.
Applications
- It is widely applied in oilfield operations including drilling, well completion, cementing, hydraulic fracturing and waste mud treatment. The product prevents water channeling and reduces friction resistance, with versatile functions such as viscosity enhancement, fluid loss control, rheology regulation, gelling, flow diversion and profile modification.
