FIELD: oil-and-gas industry.
SUBSTANCE: reservoir temporary insulation emulsion composition includes glycan amendment -biopolymer of a xantan type MC Bioxan, filler - polycell CF, non-ionogenic emulsifying agent - polyethylene glycol ether alkylphenol (OP-10), hydrocarbon fluid - waste hydrocarbon products based on oil, at the following component ratio wt %: waste hydrocarbon products based on oil 25-30, MC Bioxan 0.2-0.3, MP "Concrepol" 0.3-0.5, OP-10 2-3, polycell CF 3-5, the rest is water.
EFFECT: reservoir insulation efficiency increase because of use of the composition with structure-mechanical properties improved, biopolymer base microbiological destruction stability increase.
