The application of nonionic flocculant used in oilfield

Anion non-ionic polyacrylamide pre-hydrolyzed emulsion was used as drilling fluid material during drilling. The primary effect is to increase the viscosity of the drilling fluid, to coat, to control, to reduce the filtration loss, to protect the wall, to smooth the bit, and to make the flocculating cuttings easier to slag out. Non-ionic polyacrylamide with temperature and salt resistance is used to drive oil in the third production of oil field. Profile control and plugging use non-ionic polyacrylamide to participate in cross-linking agent for gels.
