I.Product description
80A51 is a copolymer of acrylamide and acrylic acid salt, can regulate the flow pattern to obtain shale dispersion inhibition, anti inorganic ion pollution, reduce the amount of Drilling Fluid fluid loss, increase the penetration rate and reduce downhole and reduce drilling costs in the drilling fluid and so on. Not only can be used for low solids non-dispersible polymer drilling fluid system, it can also be used to disperse drilling fluid system.

III. Features
1.80A51 is a linear polymer, after adding Drilling Fluid to maintain a smaller value of n, can effectively adjust the flow pattern.
2.Good shear thinning properties.
3.Better than the hydrolyzed polyacrylamide has coated with anti-collapse properties.
4.Can effectively reduce the amount of fluid filtration.
5.With good stain resistance and temperature resistance.
IV. On-site application
Since the successful development of 80A51, it has been popularized and applied in more than a dozen oilfields across the country, including Shengli, Liaohe, North China, Xinjiang, Jilin, Changqing, Zhongyuan, and Dagang, and has achieved huge social and economic benefits.
The usual dosage is 0.2-0.4% for fresh water slurry and 0.5-1.5% for saturated salt water slurry.
