INVESTIGATION OF MODIFIED POLYACRYLAMIDE FOR OIL DISPLACEMENT

Abstract

Introduction. At present, the use of surfactants and water-soluble polyelectrolytes, which
act as stabilizing and selective agents, is inextricably linked with the successful solution of the
technological issues in the world of chemical, oil and other industries. The purpose of the work is to
synthesize and study the physicochemical properties of modified polyacrylamide with gossypol resin and
further crosslinking in the presence of potassium persulfate and sodium sulphate to displace oil. Methods.
To establish the spectral characteristics of the modified PAA, IR spectra have been taken on an IR-Fourier
spectrometer. For the structural-elemental composition (SEM), a Jeol JSM-6490l V electron microscope
has been used. The viscosity of modified PAA solutions has been measured in a Ubellode capillary
viscometer with a hanging level. Results and discussion. The studies, carried out by the authors of the
study of the colloid-chemical properties of polymer composites, allow us to conclude that the reagents
obtained during the hydrolysis of vat residues of fatty acids distillation with sodium hydroxide with
further cross-linking in the presence of potassium persulfate and sodium sulphate have good surfaceactive and emulsifying properties, which is important when displacing oil from layers. The surface tension
of polymer compositions has been studied. With an increase in the concentration of the solution, the
surface tension decreases, i.e., the surface activity increases. Conclusion. The research results show that
the injection of a polymer reagent solution can increase the oil displacement efficiency by 6-7%.
