FIELD: oil-extracting industry.
SUBSTANCE: invention relates to special liquids used in secondary opening and damping holes. Technological liquid for perforation and damping holes comprises the following components, wt.-%: inorganic salt of alkaline-earth metal - nitrate, phosphate and their mixtures also, 0-50; universal agent RDN-U for oil extraction, 5-99.9; inhibitory salt, 0.1-10, and water, the balance. Invention provides enhancing effectiveness based on reducing time for onset of the hole exploitation, improving hydrodynamic indices of critical zone of oil layer during repair.
EFFECT: improved and valuable properties of liquid.
