FIELD: oil and gas industry.
SUBSTANCE: acid emulsion for oil reservoir bottomhole zone processing contains, wt %: solvent - reagent MIA-prom K 11.0-35.0; emulsifier-reagent ITPS-04 E 1.0-10.0; reagent ITPS - 708 A 1.1-5.5; hydrochloric acid - the rest.
EFFECT: slowing the reaction rate of acid with the reservoir rock, increase of the coverage degree by the reservoir processing, prevention of the colmatage deposits formation with the enhanced effect of the iron stabilization, the possibility to use for the bottomhole acidizing, represented by heterogeneous in permeability the carbonate reservoirs.
