polyanionic cellulose/PAC LV for oil drilling/9004-32-4
Jining Forture Biotechnology Co., Ltd welcome to visit us

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: 

 cmc oil drilling grade

(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.

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.
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.
