Micro Glass bubble 60um for cementing drilling Fluid
The Micro Glass Bubble 60µm is a high-performance solution for the oil & gas cementing industry that bridges the gap between strength and lightness. It enables operators to produce low-density cement slurries with compressive strengths, reducing well costs by decrease cement failures in challenging downhole conditions.
Advantages of Micro Glass bubble 60um for cementing drilling Fluid:
1. Density Reduction:
Traditional Lightweight systems (e.g., gas, bentonite, foamed cement) often sacrifice strength. Micro bubbles allow design of low density yet high compressive strength cements.
Example: Add 10% micro bubbles can reduce slurry density by 0.2.0 while maintaining 1500+ psi compressive.
2. Slurry Stability:
Their spherical shape eliminates “dewatering” (free water separation) and reduces the need for water required for dispersion, leading to robust, settled slurries.
3. Pumpability & Placement:
Unlike low density systems (foamed cement) which require complex equipment, micro bubble slurries are easily mixed with standard centrifugal pumps and conventional cement units.
4. Thermal & Mechanical Performance:
The bubbles act as micro aggregates, distributing stresses evenly. This improves thermal (insulation) and reduces ECD (Effective Circulation Density) during.
