Acid concentration: 15-28% HCl
fluid Viscosity (mPa·s): 20-60 mPa·s
Crosslinking time: 30-300s
Temperature resistance: Up to 160℃ (formulas adjustable for different temperatures), rheological Viscosity (mPa·s) ≥40 mPa·s.
Retardation rate: Retardation rate ≥94% (90℃, 10 min)
Corrosion rate: ≤65 g/m²·h (dynamic, 160℃)
Ferric ion stability: ≥90 mg/mL (25℃)
Broken fluid Viscosity (mPa·s): ≤5 mPa·s
Applicable scenarios:
Complex lithology reservoirs (e.g., calcareous sandstone), acid fracturing requiring high conductivity, combined acid-fracturing (acidizing + fracturing), refracturing wells prone to scaling.
Specific examples:
Acid fracturing in complex lithology reservoirs (e.g., calcareous sandstone)
Carbonate reservoirs requiring high conductivity
Combined acid-fracturing operations (fracturing + acidizing)
Ultra-high Viscosity (mPa·s) (gel-like), capable of proppant transport, forms acid-etched and proppant-supported composite fractures.
