FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil and gas industry, in particular to process fluids used for killing gas, oil and gas condensate wells. Killing fluid contains 20–40 wt.% of diesel fuel as a hydrocarbon base and 25–47 wt.% of barite with particle size of 02–90 mcm as a weighting agent. Stabilizing reagents used are 10–20 wt.% alkylbenzosulphonic acid and 10–28 wt.% oxyethylated nonylphenol.
EFFECT: easy-to-prepare and stable during storage for a long time composition for killing liquid, providing the possibility of achieving density of up to 2,5 g/cm3.
