Foam viscosity reducer
Product Description
The foaming viscosity reducer FCS-3J is suitable for reservoirs with high mineralization (mineralization above 210,000) and is used for nitrogen foam-enhanced cold production to reduce viscosity, increase oil well production, and improve recovery rates. By leveraging the excellent viscosity-reducing, profile-adjusting, and energy-enhancing properties of nitrogen foam, this product improves the injection profile, seals large flow channels, temporarily blocks shunts with foam, expands the swept volume, reduces residual crude oil saturation, and improves oil recovery efficiency.
The product is particularly suitable for heavy oil reservoirs with high viscosity, strong formation heterogeneity and insufficient energy, formations containing flow channels, low-water-cut heavy oil reservoirs, and reservoirs with bottom water.
Product Features
1. Extremely high resistance to mineralization, suitable for reservoirs with high mineralization levels (210,000 or higher).
2. Used for nitrogen foam-enhanced cold production to reduce viscosity, increase oil well production, and improve recovery rates.
3. Utilizes the excellent viscosity-reducing, profile-adjusting, and energy-enhancing properties of nitrogen foam to improve the injection profile.
4. Fully leverages the synergistic effect of foam and viscosity reducers.
Expands the swept volume, reduces residual crude oil saturation, and improves oil recovery efficiency.
Mechanism of Action of Foaming and Viscosity-Reducing Agents
Application
Suitable for foam injection and viscosity reduction in heavy oil reservoirs characterized by high viscosity, strong formation heterogeneity, and insufficient energy; reservoirs containing flow channels; low-water-content heavy oil reservoirs; and heavy oil reservoirs with bottom-water contact.
