ОСОБЕННОСТИ ПОЛИМЕРНЫХ АГЕНТОВ ДЛЯ ПОВЫШЕНИЯ НЕФТЕОТДАЧИ ПЛАСТОВ

The study of the properties of amphiphilic polymers, effectively proven in oil fields by oil recovery agents, is due to the specificity of reservoir parameters, physico-chemical properties and surface-dispersed characteristics of the formation. A characteristic feature of domestic raw materials, such as high density, viscosity, paraffin with a high sulfur content, determine the need to choose an effective method of exposure to displace raw materials.

             The paper attempts, based on a qualitative analysis of the water-oil system, to investigate in the presence of accompanying components that can affect the physicochemical properties and effects of polymers in the oil-water system. The influence of the degree of mineralization of waters on the process of displacement of high-viscosity oils has been studied, since deposits with high-viscosity oils are often accompanied by highly mineralized reservoir waters. The physicochemical characteristics of oil, reservoir water and the water-oil system have been studied in order to find ways to efficiently develop hard-to-recover oil reserves.  The influence of the polymer on the thickening properties in the oil–water system and as emulsifying agents contributing to the aggregative stability of the oil emulsion is revealed.
