Abstract

Abstract: An oil-displacing system of prolonged action with adjustable viscosity based on surfactant inorganic acid adduct and polyol is created with the purpose to increase the efficiency of flooding or thermal steam formation treatment and to enhance oil recovery. The laboratory studies of physicochemical, rheological, and filtration characteristics of the system under natural exploitation conditions and thermal-steam treatment are presented. In 2014-2018 the field tests of the technology for enhanced oil recovery were successfully carried out using an acid oil-displacing system at the experimental sites of the Permian-Carboniferous reservoir of the high-viscosity oil of the Usinsk oilfield.
