Oil drilling grade CMC/PAC is a high-purity, high-efficiency slurrying agent. It is resistant to salt, base and moisture, compatible with sea water and saturated brine. It is a strong thickener, suitable for in-situ preparation with dry powder.
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.
