PAC Polyanionic Cellulose with excellent high viscosity,low viscosity especially usages in drilling

PAC Polyanionic cellulose is a non-toxic water-soluble cellulose product using in wide areas. Its appearance is white and yellowish powder and easily soluble in both cold and hot water. It is chemically different kind of cellulose existing in wood and cotton liters. It has high resistance to salt and good heat stability. PAC Polyanionic cellulose is kind of cellulose with high uniformity and high degree substitution. It has excellent heat-resistant stability, salt tolerance and strong capability of anti-bacterial contamination. This product also prevents well collapse by means of having stabilizing properties

Polyanionic cellulose

Polyanionic cellulose is using in drilling, textile, papermaking and some of other industrial process. It also has some kind of activation with the other materials for different usages. Its water resistance properties prevent fluid loss in mud. Having low viscosity and the high viscosity properties make this product more quality especially in drilling usages. The polyanionic cellulose is excellent fluid filtration reducer. It will compose with clay a thin but strong mud film in the drilling well wall to protect the drilling well. The PAC HV could increase viscosity of the drilling fluid and suspend the drilling cuttings and particles.

PAC POLY ANIONIC CELLULOSE APPLICATION

Poly anionic cellulose in drilling This product used as filtration reducer and inhibitor, and mud. If PAC Polyanionic cellulose compares with CMC, it has better uniformity of response, with higher degree of substitution, better transparency and excellent resistance to salt and heat. It can create high-volume mud and cause low-volume loss, according to the test of OCMA. Polyanionic cellulose in work-over Adding PAC can prevent any dangerous situation (being blocked or collapsing) in production process by making this fluid stiffer. Because of its low water loss properties  PAC work-over fluid can reduce water that goes into productive zone, and the water that enters into productive The benefits of PAC polyanionic cellulose work-over  provides more than any other same products do: Avoid any damage from productive zone during process, clean drill hole and reduce maintenance to drill hole; Block filtration of water and mud and cause less bubbling; Store or can be used from one well to another, with lower cost than that of any other same products. Polyanionic cellulose’s in fracturing It made with PAC is resistant to 2% KCL solution It features good dissolvability and easy to use. PAC Polyanionic cellulose can be prepared on engineering field and gum forming is fast, with strong ability of carrying sand. If applied to the stratum of low osmotic pressure, its fracturing effect is more remarkable.

Polyanionic cellulose Storage

PAC polyanionic cellulose must be stored and seal in the dry and ventilated place to prevent from rain. high temperature and strong sunlight. The shelf life of liquid product is 6 months and that of solid product is 12 months.
