Summary
CMC-HV is produced by carboxymethyl and cellulose combined first, and then Neutralized with alkali. It is a white or pale yellow powder. It has the good capabilities of no-stink smile, no-toxic, odorless, high-hygroscopicity and form the viscosity liquid in water. It is a poly-anion electrolyte, non-fermentation, high resistance of salt and thermal stability. It is a high-effective fluid loss with resistance of high-temperature and anti-slat in drilling liquid.

 

Properties
The high viscosity of CMC can increase the viscosity of drilling liquid; can ensure the high proportion of material suspension. It has ability of against high temperature and improving the output of oil stratum.
The technology is simple on-site, convenience of maintaining, less dosage and low cost.
Non-toxic, innocuous and non-pollution.

Application
It widely used in drilling project and formation of cement mud, control the water loss and prevent the collapse of wall caused by fluid loss. Add in the mud mainly made of move soil, it’s can control the viscosity of mud. It has the advantages of non-fermentation, low shearing force and the drillings cannot sink if in static, if the mud treaded by CMC.
Suggested concertration is 0.1% to 0.2% in fresh water mud and 0.5% to 0.8% in saturated salt water mud.
