CMC for Oil Drilling Description Physical properties: a) Item: CMC
b) Appearance: free flowing off white powder c) Moisture content: 10.0% max d) PH of solution: 6.0 - 8.5 e) Particle size: 99% min., can pass through 90mesh
Advantages:
1. High degree of substitution, good uniformity of substitution.
2. High transparency, viscosity and water loss can be controlled.
3. Suitable for fresh water, sea water, saturated brine slurry.
4. Stabilize soft soil structure; prevent collapse of wall of a well.
5. Can improve mud-making volume, reduce filtration loss.
6. Has excellent performance in drilling of oil.
