FIELD: oil and gas production.
SUBSTANCE: invention relates to formulations serving to intensify functioning of injection and producing wells and can also be utilized for controlling development of oil deposits, for completing as drilled and repaired wells, for cleaning hole from salt deposits, and for cleaning tubing. Formulation according to invention contains surfactant, in particular water-, oil-, and water-and-oil-soluble surfactant or surfactant mixture, 0.5-10.0%; polymer, in particular anionic polymer emulsion in oil, 0.01-5.0%; finely dispersed hydrophobic material, 0.1-2.5%; salt-deposition and corrosion inhibitor, 0.1-1.5%; and mineral acid or mineral acid mixture, or mineral acid/organic acid mixture, in balancing amount. Formulation may further 5.0 to 20.0% of hydrocarbon.
EFFECT: improved performance characteristics due to improved rheological properties and heat resistance and enhanced oil-driving properties.
