FIELD: mining.
SUBSTANCE: invention relates to the mining industry, particularly to the liquid used as a process liquid for well perforation during re-drilling of productive formations, well killing, reperforation, perforation of additional intervals in the process of overhaul of wells. The liquid for well killing operations contains (vol.%): surface-active substance - wetting agent "ИВВ-1", "ГИПХ-6Б", "СНПХ-ПКД-515" or Sinol-KAm 1-2, flotation reagent - Oksal is the rest.
EFFECT: increase of phase velocity of filtration of hydrocarbonaceous liquid in the terrigenous reservoir, increase of inhibiting action of hydration of clayey inclusions in the formation, reduction of moisture film cohesion on the boundary with the hydrocarbonaceous liquid and display of de-emulsifying properties of the liquid.
