FIELD: oil and gas industry.
SUBSTANCE: invention relates to a method for inhibiting the formation of scaling of an oil-bearing formation, characterized by that a water-based composition is introduced into the bottomhole formation zone, which includes 3-aminopropyltriethoxysilane (APTES) in amount of 1 to 20 wt.% of the composition and nitrilotrimethylphosphonic acid (NTP) in amount of 0.1 to 3 wt.% of the composition. Invention also relates to a composition.
EFFECT: high efficiency of inhibiting salt deposition due to prolonged release of the inhibitor.
