Hei Shan Wancheng Bentonite – Premium Sodium Bentonite Drilling Fluid

Introduction: What is Sodium Bentonite Drilling Fluid?
Sodium Bentonite drilling fluid, also known as bentonite mud, is a high-performance fluid made from natural clay minerals. It is widely used in oil & gas drilling, geothermal projects, water well drilling, and geotechnical applications. This drilling fluid offers exceptional swelling capacity, gel strength, and rheological properties, which are essential for maintaining borehole stability, carrying cuttings, and controlling fluid loss during drilling operations.

Type of Bentonite
Hei Shan Wancheng Bentonite drilling fluid uses premium Sodium Bentonite, a natural clay mineral rich in montmorillonite. When mixed with water, Sodium Bentonite swells and forms a viscous gel. This property makes it ideal for drilling operations where stability, sealing, and cutting transport are critical. Unlike other bentonite types, Sodium Bentonite offers superior gel strength, high viscosity, and consistent performance under varying temperatures and drilling conditions.

Key Strengths of Hei Shan Wancheng Bentonite Drilling Fluid

1. High Swelling Capacity: Sodium Bentonite can swell up to 15 ml/g when hydrated, forming a gel that seals borehole walls and minimizes fluid loss. This ensures stable drilling conditions, even in unstable soils or challenging formations.

2. Superior Viscosity and Gel Strength: The fluid maintains its viscosity and gel strength throughout the drilling process. This allows for efficient cutting suspension, smooth flow, and borehole support.

3. Rheological Properties: Excellent flow behavior enables smooth circulation, effective cuttings removal, and reduced friction during drilling.

4. Cooling and Lubrication: Reduces heat and friction on drilling tools, prolonging equipment life and improving operational safety.

5. Environmental Compliance: Sodium Bentonite is non-toxic, biodegradable, and environmentally friendly, making it suitable for sensitive drilling environments.

Applications of Sodium Bentonite Drilling Fluid

Oil & Gas Exploration: Stabilizes boreholes, controls fluid loss, and ensures efficient drilling for petroleum extraction.

Geothermal Drilling: Maintains borehole stability under high temperatures and minimizes thermal stress on equipment.

Horizontal Directional Drilling (HDD): Provides lubrication, cutting suspension, and precise path control for underground installations.

Water Well Drilling: Ensures stable boreholes, prevents sedimentation, and supports safe extraction of drinking and irrigation water.

Geotechnical and Environmental Drilling: Stabilizes boreholes, supports soil testing, and reduces contamination risk in sensitive projects.

How to Use Hei Shan Wancheng Bentonite Drilling Fluid

1. Mixing: Combine dry Sodium Bentonite with water to achieve complete hydration and gel formation. Allow sufficient time for the bentonite to swell fully (usually 15–20 minutes).

2. Viscosity Adjustment: Monitor fluid viscosity to ensure proper cutting suspension and efficient pump operation. Adjust as needed to maintain optimal drilling performance.

3. Application: Inject prepared drilling fluid into the borehole to stabilize walls, suspend cuttings, lubricate tools, and maintain cooling.

4. Continuous Monitoring: Regularly check pH, density, gel strength, viscosity, and filtration rate to maintain consistent performance throughout drilling operations.
