Product Description
The characteristics Of FUSHIXIN's PAC polyanionic cellulose
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:
(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.

FUXIN® PAC & CMC can be used in drilling fluid, fixing fluid and fracturing fluid. In drilling fluid, it works as viscosifier, filtration reducer, and rheology controller; in fixing fluid, it is used to control fluid viscosity, suspend heavy objects, and avoid fluid loss; in fracturing fluid, it is used to carry stuffing and avoid fluid loss. And PAC also used as a thickener for low-density brines, as rheology modifier.
When CMC is used in fracturing fluid, it can bring 'stuffing' into the cracks of oil well in high efficiency and establish osmosis channel, which can effectively prevent fluid entering into oil well structure, reduce fluid loss, and lower the pressure.
The ultra high viscosity products can replace guar gum, reduce the production cost.
Instant products, like the granular PAC, used in severe environment, it will be more convenient and simpler, and it will be more effective in mud allocating.
Applications in Fresh Water, Sea Water and Saturated Water
1. Improves filtercake lubricity.
2. Stabilizes fluid rheology.
3. Cost effective, small usage, high yield.
4. Excellent salt tolerance and anti-bacteria property, convenient to use.
5. Outstanding API filtration control and suspending ability. Improve the viscosity significantly.
6. Environment friendly
Applications in Drilling Fluid
1. Protect the wall of oil well, prevent mud flowing away and carry crumbs.
2. Protect drilling bit and increase drilling speed.
3. In low solid or none solid drilling fluid, it can reduce the fluid loss and the thickness of the mud cake obviously.
4. Strong inhibition effect to shales swelling and disintegration.
Applications in Fixing Fluid
1. Protect the wall of the oil well, stop the fluid entering into the pores or cracks.
2. Control the fluid viscosity, heavy object suspension, and prevent fluid loss.
