Kémiai harmadlagos kőolajkitermelésre alkalmas polimer-tenzid oldatok folyási tulajdonságainak hőmérsékletfüggése

Abstract

High-performance emulsifiers and surfactants are used in enhanced oil recovery (EOR). During the polymer-surfactant flooding flow modifier polymer and surfactant are mixed, which reduce the surface tension. It allows to control the mobility and to increase the efficiency of the production. The rheological behaviour of the polymeric, aqueous solutions of surfactants was analysed and their effect on the temperature was studied. The movability of the injected fluid can be predicted by the rheological results which is a significant property for the oil production. Furthermore, informations related to the structure of the polymer-surfactant associates can be obtained by the rheological caracteristics.
