Product Introduction:
Polyanionic Cellulose sodium salt (PAC) is a white or slightly yellow powder that is non-toxic and odorless. It can dissolve in water, has good heat stability and salt resistance, and strong antibacterial properties. Low viscosity PAC is a high-quality, low molecular weight, and low viscosity cellulose polymer, while high viscosity PAC is a high-quality, high molecular weight, and high viscosity cellulose polymer. The mud fluid formulated with this product has good water loss reduction, inhibition, and high temperature resistance. Widely used in oil drilling, especially saltwater wells and offshore oil drilling.
Product Application:
Food Industry: Used as a thickener, stabilizer, and emulsifier in dairy products, sauces, dressings, ice creams, and beverages to improve texture and mouthfeel.
Pharmaceutical Industry: Employed as an excipient in tablets, capsules, and suspensions to enhance stability, control drug release, and improve the overall formulation's performance.
Oil & Gas Industry: Utilized in drilling muds and fracturing fluids to improve viscosity, suspend solids, and reduce fluid loss.
Textile Industry: Acts as a thickener and binder in textile printing pastes, enhancing color fastness and print quality.
Personal Care & Cosmetics: Used in shampoos, conditioners, lotions, and creams to provide viscosity, emulsification, and film-forming properties.
Paint & Coatings Industry: Enhances the viscosity and stability of water-based paints, coatings, and adhesives, improving application and durability.
Paper & Pulp Industry: Acts as a retention aid and drainage improver, enhancing paper strength and reducing production costs.
Advantages:
Application in engineering fields such as oil and gas drilling and well digging
Drilling fluid and completion fluid technology are important components of petroleum drilling engineering, playing a critical role in ensuring safe, high-quality, and rapid drilling. As a type of treatment agent used to adjust the performance of drilling and completion fluids, the main function of cellulose derivatives is to reduce filtration and increase viscosity.
It is generally believed that the mechanism of reducing filtration loss by polyanionic cellulose is mainly to improve the coalescence stability of the system by forming an adsorption solvation layer on the surface of drilling fluid clay particles; By providing protection to clay fine particles, it hinders the bonding and enlargement of clay fine particles; Reduce the permeability of the mud cake by increasing the viscosity of the filtrate and blocking the pores.
Polyanionic cellulose is easily dispersed in all water-based drilling fluids, suitable for drilling fluids from freshwater to saturated saltwater. In low solid and solid free drilling fluids, it can significantly reduce filtration loss and thin mud cake thickness, and has a strong inhibitory effect on shale hydration.
