Higher detergency of water solutions of surface active agent (SAA) to remove oil from solid surfaces as compared to water is the basis of chemical enhanced oil recovery methods. However the mechanisms of detergent action of surfactants have been insufficiently investigated yet due to the lack of relevant methods of research. The experimental set-up developed in this paper is the first to study the kinetics of oil slick washing with water solutions of surfactants from a solid surface in a wide temperature range of 25° C — 75°C. It is revealed that the difference between the detergency of water solution of the surfactant and the water begins to decrease sharply at temperatures above 60° C. For this reason, flooding of deep-lying oil reservoirs with high reservoir temperature by surfactants solutions is inefficient and unprofitable. A number of unsuccessful field tests of this technology can be caused by this effect in particular.References:
