The authors of the article consider the results of experimental testing the thermal stability of polyacrylamide-based gel-forming compounds cross-linked by chromium (III) acetate, used in enhanced oil recovery technologies. The results of the study are used to select the composition for the development site conditions. Based on the analysis and test results, ways to increase the stability of cross-linked polymer systems in high-temperature reservoir conditions are proposed.
