Polyanionic cellulose (PAC) is a water-soluble cellulose ether derivative prepared by chemical modification of natural cellulose. It is an important water-soluble cellulose ether. It is usually used as its sodium salt and is widely used in oil drilling, especially salt water wells and offshore oil drilling. PAC-Application In Petroleum 1. The functions of PAC and CMC in oil field are as follows: - The mud containing PAC and CMC can make the well wall form thin and hard filter cake with low permeability and reduce the water loss; - After adding PAC and CMC into the mud, the drilling rig can obtain low initial shear force, make the mud easy to release the gas wrapped in it, and quickly discard the debris in the mud pit; - Like other suspended dispersions, drilling mud has a certain existence period, which can be stabilized and extended by adding PAC and CMC. 2. PAC and CMC have the following excellent performance in oilfield application: - High degree of substitution, good uniformity of substitution, high viscosity and low dosage, effectively improving mud service efficiency; - Good moisture resistance, salt resistance and alkali resistance, suitable for fresh water, seawater and saturated brine water-based mud; - The mud cake formed is of good quality and stable, which can effectively stabilize the soft soil structure and prevent shaft wall collapse; - It is suitable for mud systems with difficult solid content control and wide variation range. 3. Application characteristics of PAC and CMC in oil drilling: - It has high water loss control ability, especially efficient fluid loss reducer. With low dosage, it can control water loss at a high level without affecting other properties of mud; - It has good temperature resistance and excellent salt resistance. It can still have good water loss reduction ability and certain rheology under a certain salt concentration. The viscosity is almost unchanged after dissolving in salt water. It is especially suitable for offshore drilling and deep wells; - It can well control the rheology of mud and has good thixotropy. It is suitable for any water-based mud in fresh water, seawater and saturated brine; - In addition, PAC is used as cementing fluid to prevent fluid from entering pores and fractures; - The filter press fluid prepared with PAC has good resistance to 2% KCl solution (it must be added when preparing filter press fluid), good solubility, convenient use, can be prepared on site, fast gel forming speed and strong sand carrying capacity. When used in low permeability formation, its filter press effect is more excellent.

Mixed cementitious mortars have become a very important part of the mortar industry in Global and play anindispensable role due to the market promotion and national support of policy. In development of mortars, cellulose ether is animportant activist. Ordinary mortar is economically demanding in which cement level is small, but the requirements for its operating and machine spraying properties are still high, so sand grading and additives are important. In addition, mechanical application will become a definite tendency of development of ready-mixed mortar, cellulose ether will make mechanical application possible. Product Features Increase water demand. High water retention, prolong the operating time of the material, improve the working performance, avoid the phenomenon of crusting, and help to improve the mechanical strength of the material. Improved operating performance, provide lubrication and uniform texture, so that the surface of the material is easier to wipe, thus improving the construction efficiency, and improve the resistance to cracking of putty. Improve homogeneity, and improve vertical flow resistance. HPMC for tile adhesive Ceramic tiles have high performance and excellent work efficiency when pasted on various substrates. Skid resistance and better opening time are the key to better adhesive requirements. HPMC for wall putty HPMC is non-ionic cellulose ether made from natural cotton fiber under series of chemical processing. It’s odorless, tasteless and non-toxic white powder, can be dissolved in normal water to form a transparent viscous solution with the properties of thickening,binding, dispersing, emulsifying, film coating, suspending, absorbing, gelling, water retention and colloid protection. cellulose ethers impart the following excellent properties to mortar: 一Optimized wetting ability to the substrate 一 Advanced water retention ability 一 good spraying and pumping performance 一 Improve cement hydration by bonding strength Product Description 1) Appearance: HPMC is a nonionic cellulose ether, white grayish-white powder or granule,odorless and flavorless, soluble in cold water, glacial acetic acid, ethanol, methanol and propylene glycol, slightly soluble in acetone depending on the degree of substitutions, practically insoluble in hot water, ethylene glycol and toluene. HPMC is dissolved in a mixture of 10% methanol and 90% methylene chloride to form colloidal solutions. 2) The solution of HPMC has surface activity, high transparency, and stable performance. When heated at certain temperature, the solution becomes cloudy or forms flocculent gel. However, the solution becomes clear again after cooling. Different types of HPMC have different gelation temperatures. The solubility varies with the viscosity. The lower the viscosity, the higher solubility it has. The different types of HPMC are different in some properties and their solubility in water is not affected by pH. 3) Particle sizes: 100% pass rate in 80 mesh. 4) Apparent density: 0.25-0.70 g/mL (usually about 0.5 g/mL),specific density 1.26-1.31mL. 5) Color change temperature:190-200°C; Carbonization temperature:280-300°C. 6) Surface tension:42-56 dyn/cm (2% aqueous solution). 7) The higher methoxy content in HPMC, the lower gelation temperature, and the higher solubility in water and surface activity. 8) HPMC has some other characteristics, for example, thickening property, pH stability, retention of water, excellent film-forming property, good disperse and adhesion ability.

Polyanionic cellulose (PAC) is a water-soluble cellulose ether derivative prepared by chemical modification of natural cellulose. It is an important water-soluble cellulose ether. It is usually used as its sodium salt and is widely used in oil drilling, especially salt water wells and offshore oil drilling. PAC-Application In Petroleum 1. The functions of PAC and CMC in oil field are as follows: - The mud containing PAC and CMC can make the well wall form thin and hard filter cake with low permeability and reduce the water loss; - After adding PAC and CMC into the mud, the drilling rig can obtain low initial shear force, make the mud easy to release the gas wrapped in it, and quickly discard the debris in the mud pit; - Like other suspended dispersions, drilling mud has a certain existence period, which can be stabilized and extended by adding PAC and CMC. 2. PAC and CMC have the following excellent performance in oilfield application: - High degree of substitution, good uniformity of substitution, high viscosity and low dosage, effectively improving mud service efficiency; - Good moisture resistance, salt resistance and alkali resistance, suitable for fresh water, seawater and saturated brine water-based mud; - The mud cake formed is of good quality and stable, which can effectively stabilize the soft soil structure and prevent shaft wall collapse; - It is suitable for mud systems with difficult solid content control and wide variation range. 3. Application characteristics of PAC and CMC in oil drilling: - It has high water loss control ability, especially efficient fluid loss reducer. With low dosage, it can control water loss at a high level without affecting other properties of mud; - It has good temperature resistance and excellent salt resistance. It can still have good water loss reduction ability and certain rheology under a certain salt concentration. The viscosity is almost unchanged after dissolving in salt water. It is especially suitable for offshore drilling and deep wells; - It can well control the rheology of mud and has good thixotropy. It is suitable for any water-based mud in fresh water, seawater and saturated brine; - In addition, PAC is used as cementing fluid to prevent fluid from entering pores and fractures; - The filter press fluid prepared with PAC has good resistance to 2% KCl solution (it must be added when preparing filter press fluid), good solubility, convenient use, can be prepared on site, fast gel forming speed and strong sand carrying capacity. When used in low permeability formation, its filter press effect is more excellent.
