PHPA( partially hydrolyzed polyacylamide ) for Drilling is used for oil and gas drilling.
PHPA polymer is ideally suited for applications such as water-well drilling, mineral exploration, and construction applications.
Due to its very high molecular weight, PHPA additive is also an excellent flocculant for dewatering drilling fluids, waste pits, and sumps.
PHPA anionic polymer functions as a:
Viscosifier: As a viscosifier, the addition of partially hydrolyzed polyacylamide is a cost-effective way to generate viscosity in fresh- or low-salinity drilling fluids. Its shear-thinning capacity ensures maximum power at the bit under high shear while retaining excellent carrying capacity under low-shear conditions.
Flocculant: As a flowline flocculant, anionic polyacrylamide can also be used for clear- water or low-solids drilling. Adding a 5% solution of anionic polymer into the flowline or just prior to any mechanical separation greatly enhances the removal of drill solids.
Friction Reducer: Adding PHPA polymer into a drilling fluid helps to reduce turbulent flow, friction, and power losses at points of high shear. Lowering turbulent flow also helps reduce erosion and washouts of fragile geologic structures.
Add slowly and uniformly through a high-shear jet-type mixer. Continue to circulate and agitate the slurry until all materials are dispersed and dissolved.
