---|---|---|---|
Application: | Drilling Fluid | Type: | Viscosifier |
Appearance: | Off-white Powder | Grade: | High Viscosity |
High Light: | drilling mud additives,filtration control agent |
Drilling Fluid Additives high viscosity filteration contral viscosifier
♦ high transparency, can control the viscosity and water loss reduction;
♦ suitable for fresh water, sea water, saturated salt water base mud;
♦ stability of soft soil structure, prevent the borehole wall collapse;
♦ can improve the pulp volume, reduce the amount of filtration;
♦ has excellent performance in drilling.
♦ To join in the ceramic glaze as a flow control agent, it has the performance of retain glost substitute, to prevent the glaze before firing off into tears,at the same time can burn out.

Oil-Drilling Grade CMC’s Function:
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 soluble salts.
6 . Slurry with CMC has excellent stability and will still reduce the filtration loss under 150℃ or above.
