Shale stabilization additive for water-sensitive formation
Eco-friendly drilling fluid film-forming agent
Salt-resistant high temperature wellbore stabilizer.
Cost-effective drilling fluid additive.
SCM-B is a cationic polymer-based membrane-forming additive engineered to stabilize wellbore walls in water-sensitive and dispersive formations (e.g., shale, saltwater layers). It forms a semi-permeable film on formation surfaces to inhibit fluid invasion and mitigate collapse risks。
Rapid Film Formation & Wellbore Protection: Forms a nano-scale dense hydration barrier film on wellbore surfaces within ≤15 minutes to prevent fluid invasion
Clay Dispersion Inhibition: Reduces formation hydration expansion by >40% via charge neutralization and polymer encapsulation
Salt/Ca²⁺ Contamination Resistance.
High-Temperature Stability: Retains ≥90% film strength after aging at 180°C for 16 hours.
Application Scenarios & Recommended Formulations
Mixing Procedure:
Base Fluid Prep: Adjust pH to 8.5–9.5 using NaOH/KOH.
Additive Blending:
Gradually add SCM-B at 800–1200 rpm for 20 min.
For HTHP conditions: Supplement with 1–2% sulfonated lignite.
Performance Monitoring:
Measure fluid loss every 2 hours using API filter press.
Adjust viscosity with CMC-HV or XC polymer as needed.
It is advisable to conduct laboratory tests or field trials to determine the optimal dosage for specific drilling operations.
Packaging: 25 kg triple-layer kraft bags
