Usually we use non-ionic polyacrylamide is for sewage, wastewater treatment. In fact, it is much more than that, in the oil field and drilling can play a great role. Non-ionic polyacrylamide can be called "additives" is not unreasonable. Here is a detailed explanation for you:
Anionic non-ionic polyacrylamide pre-hydrolyzed emulsion was used as drilling fluid. The primary effect is viscosity increase, coating, inhibition, filtration loss reduction, wall protection, smooth drill bit, flocculated cuttings more easily slag. Non-ionic polyacrylamide with temperature resistance and salt tolerance is used to drive oil in the third production of oil field. Profile control and leak plugging are mostly performed with non-ionic polyacrylamide crosslinking agent.
What is the effect of non-ionic polyacrylamide as a dispersant?
Mainly used in paper dispersant and textile sizing assistant. The primary effect of paper dispersant is to make fiber and filler more evenly distributed in the paper, so that the paper evenly smooth without holes. The primary effect of textile sizing agent is to make the slurry on the fabric, to achieve the effect of smooth, thick and full, stiff fabric.
What is the effect of non-ionic polyacrylamide in shale gas fracturing?
It can be used as a drag reducing agent for fracturing, because in order to reach the application conditions of the site, more soluble non-ionic polyacrylamide emulsion and non-ionic polyacrylamide fine powder products are used to reach the effect of reducing rough fluid turbulence in the pipeline and reducing molecular movement resistance.
