Abstract

FIELD: oil/gas production. SUBSTANCE: oxygen-containing organic composition, water solution of metal nitrate or mixture of metal nitrates related to beryllium group, bismuth, cadmium, cobalt, manganese, copper, nickel, lead, strontium, aluminum, iron, chromium, tin are pumped subsequently with nitrate content in water solution within the range from 2.0 per cent by weight to the concentration corresponding to saturated solution, and 18 - 35 per cent by weight water solution of hydrochloric acid. Nitrate water solution may content non-ionogenic surface-active substances or mixture of non-iogenic surface-active substances with total content of those in nitrate water solution within 0,001 - 5.0 per cent. Hydrocarbon acid water solution may contents anion, cation, non-ionogenic surface-active substances or mixture of those with hydrocarbon acid water solution with total content of those within 0.001 - 5.0 per cent. EFFECT: increased well productivity.

Изобретение относится к нефтедобывающей промышленности, а именно к термохимической обработке призабойной зоны скважины. Целью изобретения является повышение производительности скважины за счет увеличения глубины обработки и разглинизирующей способности рабочих жидкостей, а также снижения уровня взрывоопасности при работах. Это достигается тем, что в скважину последовательно закачивают кислородсодержащее органическое соединение, водный раствор нитрата или смеси нитратов металлов из группы бериллия, висмута, кадмия, кобальта, марганца, меди, никеля, свинца, стронция, алюминия, железа, хрома, олова при содержании нитратов в водном растворе от 2,0 мас.% до соответствующего насыщенному раствору и водный 18 - 36 мас.%-ный раствор соляной кислоты. Водный раствор нитратов может содержать неионогенные поверхностно-активные вещества или смеси неионогенных поверхностно-активных веществ при общем содержании их в смеси с водным раствором нитратов 0,001 - 5,0 об. %. Водный раствор соляной кислоты может содержать анионные, катионные, неионогенные поверхностно-активные вещества или их смеси при общем содержании их в смеси с водным раствором соляной кислоты 0,001 - 5,0 об.%.The invention relates to the oil industry, namely to thermochemical treatment of the bottom-hole zone of the well. The aim of the invention is to increase the productivity of the well by increasing the depth of processing and the decontaminating ability of the working fluids, as well as reducing the level of explosion hazard during work. This is achieved by the fact that an oxygen-containing organic compound, an aqueous solution of nitrate or a mixture of metal nitrates from the group of beryllium, bismuth, cadmium, cobalt, manganese, copper, nickel, lead, strontium, aluminum, iron, chromium, and tin are sequentially pumped into the well with a nitrate content in an aqueous solution from 2.0 wt.% to the corresponding saturated solution and an aqueous 18 - 36 wt.% - hydrochloric acid solution. An aqueous solution of nitrates may contain non-ionic surfactants or mixtures of non-ionic surfactants with a total content of mixed with an aqueous solution of nitrates of 0.001 to 5.0 vol. % An aqueous solution of hydrochloric acid may contain anionic, cationic, nonionic surfactants or mixtures thereof with a total content of 0.001 to 5.0 vol.% In a mixture with an aqueous solution of hydrochloric acid.
