Applications:
It is mainly used in the oil drilling field, enhancing the viscosity of drilling fluid, improving dispersion performance and reducing the friction coefficient. Additionally, it can seal fractures and loose formations to prevent drilling fluid loss. The product forms a space grid structure with clay particles, providing excellent shear-thinning properties. Its flocculation capability aids in cleaning the well bottom, and multi-point adsorption helps prevent borehole collapse.
Specific Functions:
1. Inhibiting hydration and dispersion of clay and drill cuttings. Potassium polyacrylamide, due to its special chemical structure, effectively inhibits the hydration and dispersion of clay and drill cuttings, thereby preventing downhole instability incidents such as formation collapse and lost circulation.
2. Controlling formation mud-making. During drilling operations, formation mud-making can affect drilling fluid performance. Potassium polyacrylamide effectively controls formation mud-making, thereby maintaining drilling fluid stability.
3. Enhancing drilling safety and success rate. Potassium Polyacrylamide significantly improves drilling safety and operational success through excellent inhibition and sealing properties, effectively reducing incidents such as lost circulation and wellbore collapse.
4. Reducing environmental pollution. The use of potassium polyacrylamide in drilling fluids can reduce environmental contamination caused by drilling mud and enhance environmental protection.
Product Advantages:
1. Good solubility, low corrosiveness, low dosage, and stable performance.
2. Neutral pH, wide application range, and non-corrosive to equipment.
3. Low-salinity drilling fluid with reduced sludge yield.
4. Effective removal of heavy metals and radioactive substances.
Usage and Dosage: Typically 0.1%–0.6% (v/w). Do not add the product directly into the mud pit; instead, prepare a diluted aqueous solution (usually 0.5%–1%) before addition.
Packaging: 25kg/bag, packed in paper-plastic composite bags (Customizable according to client specifications).
Storage Conditions: During storage and transport, store in a dry, cool, and well-ventilated warehouse, keep away from fire sources and heat, and avoid direct sunlight.
