Main Advantage & Solution

  • 1: Chromium-containing additives violate environmental regulations;
    Solution: Chromium-free formula, no harm to humans/livestock/environment, meets global environmental standards.
  • 2: Poor thermal stability in medium-temp wells;
    Solution: Maintains performance at 150°C, HTHP fluid loss ≤25ml.
  • 3: Single-function additives require multiple additions;
    Solution: Synergistic effect with sulfonated phenolic resins, enhances salt resistance and fluid loss control.
