Beschreibung
Zusammenfassung:	FIELD: oil and gas industry. ^ SUBSTANCE: invention refers to oil and gas producing industry, specifically to well killing liquids and can be used in repairs of holes of formation pressure equal or lower that hydrostatic one. Well killing liquid contains, wt %: SEANEC-TU or MC Bioxan - 0.4-1.0; diethylene glycol - 15-25; calcium chloride - 5-10; Morpen - 0.5-1.0; water - the rest. ^ EFFECT: higher efficiency of well killing due to liquid with improved structure-rheological properties, and hence, with low fluid losses thus proving reservoir retention and reducing well development time with higher frost resistance, higher microbiological destruction stability of biopolymer base, bactericide diversification. ^ 3 tbl, 5 ex
