The results of experimental investigations of fluids with nanoparticles, designed for bed and wellbottom zone stimulation, are presented. An aqueous solution of anionic surfactant with additives of nanoparticles of light nonferrous metal is considered. It is shown that the resulting fluid can reduce the surface tension on the border with oil compared with an aqueous solution of surfactant and is characterized by a shear thinning. It is concluded, that the use of nanosuspension allows to enhance significantly the efficiency of oil displacement and filtering.
