Abstract

FIELD: oil production. SUBSTANCE: dissolver fringe is pumped in the stratum, then fringe of surface-active substance dispersion and alkali, with fringe of the dissolver and dispersion pumped in at relationship of volumes ranging from 1:1 to 1:20 respectively followed by forcing through by water. The method may be applied at the beginning, middle and late stages of oil field exploitation. EFFECT: higher efficiency. 3 cl, 2 tbl

Изобретение относится к нефтяной промышленности, в частности к разработке нефтяных месторождений, и может быть использовано для повышения нефтеотдачи карбонатных и терригенных пластов с повышенной неоднородностью, содержащих высоковязкие нефти. Цель изобретения - повышение эффективности способа. В пласт закачивают оторочку растворителя, затем оторочку дисперсии поверхностно-активного вещества и щелочи на закачиваемой воде, причем оторочку растворителя и дисперсии закачивают при соотношении объемов от 1:1 до 1: 20 соответственно с последующей продавкой водой. Способ повышения нефтеотдачи может быть применен на начальной, средней и поздней стадиях разработки нефтяных месторождений.The invention relates to the oil industry, in particular to the development of oil fields, and can be used to increase oil recovery of carbonate and terrigenous strata with increased heterogeneity, containing highly viscous oils. The purpose of the invention is to increase the efficiency of the method. The rim of the solvent is injected into the formation, then the rim of the dispersion of the surfactant and alkali on the injected water, and the rim of the solvent and dispersion is injected with a volume ratio of 1: 1 to 1: 20, respectively, followed by selling with water. The method of increasing oil recovery can be applied at the initial, middle and late stages of oil field development.
