Реагент получают путем простого смещени компонентов. Он представл ет собой жидкость, хсУрошо растворимую в воде.The reagent is obtained by simply displacing the components. It is a liquid that is soluble in water.
Реагент используют следующим образом.The reagent is used as follows.
Предварительно подготовленный рабочий водный раствор смеси или смесь без.специальной подготовки дозируют в закачиваемую в пласт воду в необходимой концентрации. В зависимости от свойств пласта может быть осуществлена непрерывна закачка с добавкой 0,001-0,01% смеси или периодическа обработка нагнетаемой в пласт воды ее повьииенной концентрацией.The previously prepared working aqueous solution of the mixture or the mixture without special preparation is metered into the water injected into the reservoir at the required concentration. Depending on the properties of the reservoir, continuous injection with the addition of 0.001-0.01% of the mixture or periodic treatment of the water injected into the reservoir with its concentration can be carried out.
Эффективность подавлени роста сульфатвосстанавливак цих бактерий определ ют по оценке защитного действи реагентов, подавл ющих микробиологическую коррозию, следуюащм образом: в промысловую воду, содержащую сульфатвосстанавливаювдие бактерии (СВБ), в стерильных анаэробных услови х ввод т реагент в соответствуювдах концентраци х и вьвдерживают 24 ч при 32°С.
