FIELD: chemistry.
SUBSTANCE: invention relates to a composition for preparing high-density non-solid phase liquid which can be used in oil and gas industry in capping and repairing and oil and gas wells under conditions of abnormally high formation pressure and high temperature, for drilling out salt deposits, primary and secondary drilling of producing formations. The composition for preparing high-density non-solid phase process liquids contains the following in wt %: calcium nitrate 31.20-49.0, zinc chloride 0.20-37.59, zinc oxide 0.01-1.80, calcium chloride - the rest.
EFFECT: low toxicity with preservation of processing properties.
