FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil and gas industry, in particular to process compositions for well killing, and can be used at oil and gas producing enterprises during various types of repair works in oil and gas wells, as well as during overhaul of wells at underground gas storages. Fluid contains sulfacell, water and zinc iodide, with the following ratio of components, wt.%: sulfacell 1.5–2.0; zinc iodide 65.0–70.0; water – balance.
EFFECT: increasing the efficiency of killing wells with reservoir pressure higher than hydrostatic through the use of fluid for killing wells without a solid phase with increased density.
