Polyacrylate de potassium (K-PAM)

Polyacrylate de potassium (K-PAM)

Potassium polyacrylate (K-PAM) is a high-performance shale inhibitor. It excels in resisting mud contamination and controlling both viscosity and fluid loss. K-PAM helps stabilize the wellbore, inhibit clay swelling, and enhance drilling efficiency in fresh-water and low-solids drilling fluid systems; it is suitable for a wide range of water-based drilling fluid systems.

Potassium Polyacrylate (K-PAM) Shale Inhibitor

Product Overview

Potassium Polyacrylate (abbreviation: K-PAM), also known as potassium polyacrylamide salt, is a high-molecular water-soluble anionic polymer. It is polymerized and hydrolyzed with acrylamide and potassium hydroxide as raw materials. This product appears as white or light yellow free-flowing powder, featuring excellent water solubility, high viscosity, good temperature resistance and salt resistance. With active potassium ions inside the molecular chain, it can effectively inhibit the hydration and dispersion of clay minerals. K-PAM is widely used as drilling fluid additive, flocculant and thickener in petroleum drilling, geological exploration, mineral processing, wastewater treatment and agricultural soil improvement industries.

 Caractéristiques du produit

  • Excellent Inhibition Performance: The released potassium ions embed in clay crystal layers to prevent shale hydration expansion, effectively stabilize well walls and reduce borehole collapse risk.
  • Good Filtration Reduction Effect: Form dense and thin filter cake on the well wall, reduce water loss of drilling fluid, and protect vulnerable water-sensitive formations.
  • High Viscosity & Suspension: Increase drilling fluid viscosity, improve carrying capacity of cuttings, and prevent sedimentation of solid particles.
  • Strong Compatibility: Good compatibility with various water-based drilling muds. It has excellent compatibility with common drilling additives such as CMC, sulfonated lignite asphalt powder and xanthan gum, no adverse reaction with other mud additives.
  • Environmental & Safe: Non-toxic, non-corrosive, easy to degrade, low environmental pollution, suitable for various construction environments.
  • Stable Chemical Properties: Excellent high temperature resistance, not easy to decompose in high-temperature deep well operation, stable performance in high-salinity water quality.

Application Fields

Petroleum & Geological Drilling

Used as shale inhibitor, filtrate reducer and viscosifier for water-based drilling fluid. It effectively prevents well collapse, reduces mud loss, improves mud rheological property, and is suitable for easy-to-collapse formations and water-sensitive mud shale formations.
Mineral Processing Industry
Used as flocculant and settling agent to accelerate the sedimentation of fine ore particles, improve ore clarification efficiency, and reduce tailings water turbidity.

Wastewater Treatment

Applicable for industrial and domestic sewage purification. It flocculates suspended solids and colloidal impurities in water to achieve rapid solid-liquid separation.

Agricultural & Horticulture

Serve as super absorbent polymer for soil water retention, improve soil aggregate structure, reduce water evaporation, and improve drought resistance of crops.

Usage Method

Slowly add K-PAM powder into clean water under continuous stirring, with stirring speed controlled at 300-500 r/min. Completely dissolve within 15-30 minutes to prepare uniform aqueous solution. The recommended dosage is 0.1%-0.3% for drilling fluid, and the specific dosage shall be adjusted according to construction conditions and formation characteristics.
