摘要
FIELD: oil, gas and coke-chemical industries.;SUBSTANCE: invention relates to oil industry and can be used for intensification of development of low-productive deposits of high-viscosity oil with carbonate reservoir under natural conditions, without thermal impact. Composition for intensification of development of low-production deposits of high-viscosity oil with carbonate reservoir, containing complex surface-active substance - surfactant Neftolol WDM or mixture of nonionic surfactant - nonionic surfactant AF 9-12 or NP-40, or NP-50 and anion-active surfactant - argil peroxide or sulphonol, or NPS-6 in ratio of 2:1, boric acid and glycerine, additionally contains electrolyte: AlCl3 or FeCl3, or FeCl2, or MgCl2, with the following ratio of components, wt. %: complex surfactant or mixture of nonionic surfactants and surfactants 1.0–4.0, boric acid 1.0–5.0, glycerine 10.0–50.0, electrolyte AlCl3 or FeCl3, or FeCl2, or MgCl2 0.5–20.0, water - balance.;EFFECT: technical result is increase in the composition efficiency for the high-viscosity petroleum deposits with the carbonate reservoir conditions due to the wide range of the physicochemical, rheological, surface-active properties of composition and rate of dissolving carbonate reservoir, adjusting them under conditions of specific deposits.;1 cl, 9 ex, 4 tbl, 1 dwg
