1. Product Overview
SDL-1 Film-Forming Leak Sealer is a polymer-based drilling fluid additive specifically engineered to address fluid loss in porous and fractured formations. Utilizing advanced colloidal chemistry, it rapidly forms a semi-permeable membrane on fracture surfaces to stabilize wellbore integrity while maintaining optimal rheological properties. Compatible with water-based, oil-based, and brine mud systems.

2.Functions and Characteristics
- Instantaneous Leak Sealing: Creates a self-repairing film within 8-12 minutes, reducing fluid loss by ≥85%.
- Thermal Stability: Performs reliably at temperatures up to 180°C without viscosity degradation.
- Cost Efficiency: Reduces total mud consumption by 25-40% through targeted leak mitigation.
Primary Functions
Leakage Control:Seals porous and fractured zones to minimize fluid invasion and differential sticking risks.
Wellbore Strengthening:
Enhances near-wellbore stress resistance through membrane-induced pressure containment.
Mud System Preservation: Maintains stable rheology in high-salinity and high-solids environments.
