Abstract

Способ добычи нефти, в котором в нефтяную формацию нагнетают водную вытесняющую среду, содержащую воду, глюкан, мочевину и, при необходимости, ПАВы, и из формации, по меньшей мере из эксплуатационной скважины, извлекают нефть, причем температура формации составляет по меньшей мере 60°С. Под воздействием температур формации композиция образует в ней пену в естественном залегании.An oil production method in which an aqueous displacement medium containing water, glucan, urea and, if necessary, surfactants is injected into the oil formation, and oil is extracted from the formation, at least from the production well, and the formation temperature is at least 60 ° WITH. Under the influence of formation temperatures, the composition forms a foam in it in the natural bedding.
