CMC - Na Carboxy Methyl Cellulose In Petroleum Drilling EINECS No.
1. General Information of Sodium Carboxyl Methyl Cellulose(CMC-Na)
|Appearance||Freely flowing white powder|
|MF||C6H7 (O H)2OCH2COONa|
|Degree of substitution||0.75min|
|Filtrate Loss||10 ml max|
Carboxymethyl Cellulose Sodium (CMC-Na) is a cellulose derivative
obtained by chemically modificating the natural cellulose. It is
one of the most important water soluble polymers with many
advantages that other natural or synthetic glues do not have.
CMC is white and flowing fine powder. It is tasteless, smelless,
mould-proof, non-toxic, non-flammable and easily dissolved in water
to become transparent viscose solution.
CMC solution has good properties of thickening, adhering,
emulsifying, and stabilizing. Membrane forming, moisture-holding,
shape-holding, dispersing and anti-enzyme. The solution of CMC can
be mixed with dissolvable animal glues, glycerin, sobbitol, Arabic
gum, pectin, xanthic gum and dissolvable starch.
Its advantage is as follows:
(1) High substitution degree and good substitution uniformity;
(2) High transparency, controllable viscosity and filtrate reducer;
(3) Being suitable for fresh water, sea water, saturated brine
water base mud;
(4) Stabilized soft soil structure to prevent the collapse of shaft
(5) Being able to increase the amount of pulp and reduce the loss;
(6) Excellent performance in drilling.
2. Application and procedure of Sodium Carboxyl Methyl
Rather high control ability of water loss. PAC particularly is a
highly efficient filtration loss agent, and even less dosage can
control the water loss at a higher level, without affecting the
other properties of the mud.
(1) Good temperature resistance and salt resistance. It can still
have rheological properties and a good ability to reduce water loss
in a certain salt concentration. Its viscosity in the salt water
solution is almost the same with that in the water solution, which
is especially applicable to the requirements for drilling and deep
(2) Effective control of the slurry rheology and good thixotropy.
It is suitable for any water-based mud of fresh water, sea water
and saturated brine;
(3) PAC is used as a cementing fluid to prevent fluid from entering
the pores and cracks;
(4) Pressure filtrate capability 2% KCl solution with PAC
preparation (must be added in the preparation of leachate) is well
soluble, easy to use and convenient to prepare in the field.
Besides, it also has a fast gel-forming speed and strong ability to
carry sand. The filter effect is more remarkable in the stratum
with low penetration pressure.
3. Packing and Shipping
CMC is packed in 25 kg kraft bags with pallets.
We have rich experiences in exporting and importing. We have good
cooperation with world wide Express like DHL, UPS etc and also
shipping line to ensure the samples and goods can be reach to the
cutomers at soonest speed.
