| abstract | FIELD: oil-and-gas industry. n SUBSTANCE: method of processing for dissolution of acid-soluble material and solubilisation of hydrocarbons, emulsions and water barriers comprises the following jobs. Injection of micellar dispersion in the bed, said dispersion is a Winsor micro emulsion IV containing water, one or several precursors of organic acids, one or several surfactants and, not necessarily, one or several substances selected from salts, auxiliary surfactants and/or organic fluids which are not precursors of organic acids. Solubilisation is performed of micellar dispersion of hydrocarbons, emulsions or water barriers present in the bed and in-situ hydrolysis of, at least, a portion of organic acid precursor to produce sufficient amount of organic acid to cause notable dissolution of acid-soluble material present in filtration crests or nearby them, or other damage in the bed. Hydrolysis of organic acid precursor brings about the production of at least one of formic, acetic, hydroxiacetic and lactic acids. Organic acid precursor concentration makes at least 1 wt %. Well shutdown after introduction of micellar dispersion makes 0.5 h or more. n EFFECT: efficient one-step processing at controlled rate. n 23 cl, 5 tbl, 3 ex |
