Polyanionic Cellulose (PAC)

Molecular Formular: [C₆H₇O₂(OH)₂CH₂COONa]_n

Structural Formular:

Property：

PAC is a high purity, high DS, high viscosity, low viscosity and other non-ionic cellulose ether. These products have Demi-natural polymer additives, thickening agents, filtrate filtrate.

PAC is an important product of drilling mud. This is a high purity product; The aqueous solution of the white powder is transparent and viscous. As a water-soluble polymer, Pac dissolves immediately in cold water or hot water. can be used as thickening agent, rheological control agent, adhesives, stabilizer, colloid protector, suspension and filtrate reduction agent.

PAC is a good additive for drilling mud and is an important material for preparing oil well. With high acid, salt-resistant mud volume products. PAC is a good control agent for filtrate loss. Its ability to increase viscosity and temperature (150 ℃) in freshwater, seawater or even saturated saline liquids. The PAC is suitable for the preparation of the 3 kinds of water completion fluids.

Specification:

Note: You can adjust the parameters as needed.

Use：

PAC is used in high-pressure drilling fluids, which can effectively reduce the filtration rate of many water-based oil and gas drilling fluids, and can also be used to improve stability and viscosity, and improve the pore fluid environment of cleaning and suspension properties.

PAC is used for solid loading and water-based drilling fluids, which can effectively reduce the filtration rate of many water-based drilling fluids without causing a significant increase in viscosity or gel strength.

PAC R is a cost-effective additive in order to reduce the API filter a large amount of water drilling fluids, including freshwater, seawater, saturated saline and solids anhydrous brine, local mud, mud, mud contamination and flocculation suppression systems. PAC R increases and stabilizes viscosity, improves rheology, good cleaning and suspension properties, through coating and encapsulation of drilling and solid fluids. PAC R is effective in a wide range of ph environments. It lubricates the solids in the system, improves the wall cake characteristics, and reduces the likelihood of blocking the tube.

Encapsulation and Storage:

Pack multiple paper bags or fibre drums (25KG) or customer requirements;
