The development of composite polymers for oil displacement and improving the performance of oil wells is an urgent task. In this article, the authors made an analysis of the state of the problem of enhanced oil recovery of oil reservoirs based on water-soluble polymers. The issues of synthesis and study of the physicochemical properties of modified polyacrylamide with fatty acids, gossypol resin and further crosslinking in the presence of potassium persulfate and sodium sulphate to enhance oil recovery are considered.
