FIELD: oil and gas production.
SUBSTANCE: process fluid for perforating and killing of oil wells contains wt %: potassium chloride 9.0-24.0, water soluble surface active substance SNPH-PKD-515 1.0, corrosion inhibitor CONCOR-9510 0.01-0.04, process or sea water - the rest.
EFFECT: raised efficiency of process fluid due to adding anti-corrosion properties to it and due to additional reduction of interfacial tension on border of water-oil mediums.
