1. Product Overview
SCM-A is a high-performance cationic polymer membrane-forming agent specifically designed for water-sensitive and dispersive formations in drilling operations. It effectively stabilizes wellbore walls by forming a dense, low-permeability film (10–50 μm) through adsorption and pore-plugging mechanisms, reducing fluid invasion by ≥70%17. Manufactured by Beijing Sanhe Runjing Technology Co., Ltd.
2.Functions and Characteristics
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.
3.Technical Indicators
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.
It is advisable to conduct laboratory tests or field trials to determine the optimal dosage for specific drilling operations.
Performance Monitoring:
Measure fluid loss every 2 hours using API filter press.
Adjust viscosity with CMC-HV or XC polymer as needed.
