Description
Product Description
PHPA( partially hydrolyzed polyacylamide ) for Drilling is used for oil and gas drilling.
PHPA acrylic copolymer is an extremely high-molecular-weight, high-charge, polyacrylamide supplied as a dry granular powder.
PHPA produces very high viscosity solutions at low dosage rates, particularly in freshwater. It hasexcellent handling characteristics, mixes easily, and dissolves quickly when added to water- base fluid systems.
Typical Physical Properties:
Physical appearance: White, granular powder
Ionic character: Anionic
Density: 0.8 g/cc
Bulk density: 800 kg/m 3
pH (1% Solution): 6.0-8.0
Applications:
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.
Recommended application amounts:
Normal consolidated formation:
0.7 to 0.9 kg per 378.5 L water
Unconsolidated formation:
1.1 to 1.6 kg per 378.5 L water
Advantages:
Provides a clay-free boring fluid that disperses easily with minimal shear
Soil stabilizer can be used to replace bentonite in a typical geo-construction application
Produces very-high-viscosity slurries at low dosage rates
Slurries typically have low gel strength
Slurry binds loose sand, clay, shale, and gravel, facilitating their removal and preventing dispersal into the slurry.
Reduces fluid loss by penetrating the surrounding soil with a high-viscosity gel fluid, sealing the walls of the excavation site without the use of a conventional filter cake
Stabilizes reactive formations and is an efficient viscosifier for a clear, solids-free drilling fluid
Provides high cohesiveness to bind sandy soil and gravel
Enhances core recovery in continuous wireline coring operations
Facilitates the removal of drilled soils from augers
Non-fermenting, without petroleum distillates and easily broken down with household bleach
Cleanup
PHPA acrylic copolymer can be chemically broken down with liquid bleach in regular household concentration (5% sodium hypochlorite). Use 1 gal (3.8 L) of liquid bleach per 100 gal (378.5 L) of fluid formulated with PHPA acrylic copolymer. Do not use perfumed liquid bleach or solid calcium hypochlorite.
Toxicity and Handling
When used in accordance with the manufacturer's published instructions, this product is considered non-hazardous. Drilled cuttings exposed to PHPA should be washed with calcium hypochlorite to break down the Poly-Plus EHV acrylic copolymer before the cuttings can be confined or stored in a sealed container or drum.
Packaging and Storage
Packed in 25kg PE bag or 1000kg bag.
Should be stored inside under cool, dry conditions. When stored under these conditions, it has a shelf life of at least one year.
