Our company's PAC polyanionic cellulose
have strong water-soluble, good anti-salt, anti-calcium and magnesium, reduce
filtration loss capacity, because we adopt special processing technology to
produce PAC, it can be applied to different drilling fluid system. Especially
in salt water drilling, seawater drilling, saturation salt water drilling, and
all have a very good role in filtration loss. Compared to the CMC which
produced by conventional process, it has the following characteristics:

The performance
characteristics of CMC in DRILLING
CMC is used in the drilling
fluid loss agent, the effect is formed by on the wall of low permeability,
flexibility, thin and dense filter cake, as far as possible, reduce the amount
of drilling fluid filtration and used for low solid drilling fluid of
suspending agent, plugging agent and thickener.
(1) Uniform D.S, good transparency,
controllable viscosity and filtration loss;
(2) Fit for water-based mud of fresh water,
seawater and saturation salt water;
(3) Confected mud has good
characteristic in reducing filtration loss, restraining and enduring high
temperature;
(4) Confected mud has good rheology, it can
restrain the dispersion and expansion of shale and clay in the high-salt
medium, so that the pollution of the wall of a well under controlling;
(5) Made the soft soil structure stability
to prevent the collapse of the wall;
(6) Slowed down the accumulate of solids in the
mud, when well-drill get across the rock face;
(7) Restrained the turbulence in drill
pipe, so that the circumfluence system can maintain a minimum pressure
loss;
(8) Enhanced the yield of clay of the mud, reduced
the filtration loss;
(9) Obtained stable foam mud.
PAC is a kind of high molecular weight polyanionic
cellulose and easy to disperse in all water-based drilling fluid and it can be
used in both fresh water and saturated salt water. In low solid polymer
drilling fluid, it can significantly reduce amount of fluid loss and thin the mud
cake, and have strong inhibition to shale hydration. At the same time it has a good temperature
resistance and salt resistance.
