Annotation:
The authors of the article present the results of laboratory studies of gel-forming composition technological properties based on polyacrylamide in the range of 0,5…2,0 % concentration. In terms of rheological characteristics, polymer gels have viscous-elastic or viscous-plastic properties. The components concentration increase in the system leads to an increase of gels structural-mechanical properties, which makes it possible to use polymer compositions for water shutoff.
