High Viscosity CMC And PAC For Oil-Drilling Industry Purity ≥ 99%
|
Detailed Product Description
|
Sodium Carboxymethyl Cellulose
Product DescriptionOur PAC (oil drilling grade) and CMC are advantageous because of their: small usage, high yield; good salt tolerance, anti-bacterial property and convenient to use; the fluid loss reduction and the viscosity improvement; flowing control and strong suspending capability; environmental friendly, nontoxic, harmless and odorless; and good liquidity, convenient to construction. |

| The Function of CMC OIL-DRILLING industry | ||||||||||
| 1.CMC-containing mud makes a well wall a thin, hard and low-permeability filter cake to reduce water loss. | ||||||||||
| 2.Adding CMC into slurry will endow the drill with low initial gel strength, making the slurry give off the gas inside and abandoning the | ||||||||||
| waste into the slurry pit. | ||||||||||
| 3. Same as other suspending dispersion, the drill slurry has an existing period which will be stable and extended after adding CMC. | ||||||||||
| 4.Slurry with CMC is seldom affected by the bacterium and requires no high PH value or corrosion resistant. | ||||||||||
| 5.The wall-cleaner treatment chemicals with CMC can resist the contamination of all kinds of soluble salts. | ||||||||||
| 6.Slurry with CMC has excellent stability and will still reduce the filtration loss under 150℃ or above. |
