Product Description
1. Carboxymethyl cellulose has high degree of substitution
2. High viscosity, less addition
3. Remarkable effect
4. ISO 9001-2000
5. Abundant products
6,Name:Carboxymethyl cellulose(CMC) for Oil Drilling Grade(MV-CMC, 85%min purity).
7.We also can produce oil drilling grade CMC according to your special specification requirements.
Carboxymethyl cellulose(CMC) has good water-loss controlling ability, expecially PAC is highly effective drop filter-loss agent. Even added at low quantity, CMC can control water loss at very high level,but does not affect slurr's other characteristics.
Carboxymethyl cellulose(CMC) can form high quality slurry cake which is strong and fiexible.
Carboxymethyl cellulose(CMC) has good temperature resistance and superior anti-salt character,Under certain salt density, Carboxymethyl cellulose can remain good water-loss capability and certain rheology,so the viscosity in salt solution is the same as in water,which is specially suitable for sea misering and deep well.



OIL DRILLING GRADE
CMCis usde as filtrate reducer in drilling fluid to low permeability,flexible,thin and dense filter cake,so as to reduce the loss of drilling fliid. CMC aslo can be usde as suspending agent,plugging agent and thickening ageent solid fluid.
Good temperature resistance and salt resistance;

The prducts are little affected by the mold,thereby stabillizing and prolonging the existence peiod;

Easy to disper in all water base drilling fluids, from fresh water until saturaued brine drilling fliuid can be used;

Prevent the fluid into the porss and cracks,fracturing fluid can be used to control the loss of fluid into the well;

As an oil production and fracturing agent, improve the performance of the fractring fluid suspen-sion, can significantiy reduce the filtration loss and reduce the thin mud cake, and shale hydration has a strong inhibitory effect.
