Description
Изобретение относитс к обработке воды при заводнении нефт ных пластов в частности к составам дл бактерицидной обработки морской воды. Известны химические вещества, например хлор, озон, медный купорос и другие растворимь1е соединени меди которые примен ют дл борьбы с бактери ми и биологическими обрастани ми в промышленных системах L J. Недостатком этих бактерицидов вл етс низка эффективность по отношению к сульфатвосстанавливающим бакт ри м (СВБ). Наиболее близким- к предлагаемому по технической сущности и достигаемом результату вл етс сульфат тетрамин 2. Однако этот состав наиболее эффективно воздействует на бактерии в нейтральной среде, а оптимальное значение рН, необходимое дл жизнеде тельности СВБ, находитс в интервале 6,5 - 7,5, кроме того, присутствие мсдИ при концентрации, ниже токсичных 10 мг/л, стимулирует жизнеде тельность бактерий. При избытке аммиака и повышенной жесткости возможно выпадение осадка карбоната кальци . Целью изобретени вл етс повышение степени бактерицидной активности. Поставле:нна цель достигаетс тем, что состав дл бактерицидной обработки морской воды, включающий соединение меди и воду, в качестве которого он содержит сульфат или хлорид меди и дополнительно уротропин при следующем соотношении ингредиентов, мг/л: Сульфат или хлорид меди (в пересчете на, Са)17-21 Уротропин10-12 ВодаДо 1 л Культуру СВБ выдел Пример ют из закамиваемои в нефт ные пласты воды Каспийского мор . Состав испытывают на морской воде, зараженной СВБ. Пробу отбирают в стерильную посуду, дозируют определенное количество состава, выдерживают 2k ч при 20-22 С. Затем отбирают 4 1-2 мл пробы и ввод т в питательную среду Пост гейта. В каждом случае провод т по 3 параллельных опыта. Пробы помещают в термостат и наблюдают 15 сут . Полученные результаты представлены в таблице,The invention relates to the treatment of water in the case of a flooding of oil reservoirs, in particular, to compositions for the bactericidal treatment of seawater. Chemicals are known, for example, chlorine, ozone, copper sulfate and other soluble copper compounds that are used to combat bacteria and biological fouling in industrial LJ systems. The disadvantage of these bactericides is their low efficiency against sulfate-reducing bacteria (SRB ). The closest to the proposed technical essence and the achieved result is tetramine 2 sulfate. However, this composition most effectively affects bacteria in a neutral environment, and the optimum pH value necessary for the life of SIB is in the range of 6.5 - 7.5 In addition, the presence of MSDI at a concentration below the toxic 10 mg / l stimulates the viability of bacteria. With an excess of ammonia and increased rigidity, calcium carbonate may precipitate. The aim of the invention is to increase the degree of bactericidal activity. The goal is: the composition for the bactericidal treatment of sea water, including a copper compound and water, in which quality it contains copper sulfate or chloride and additionally hexamine in the following ratio of ingredients, mg / l: Copper sulfate or chloride (in terms of , Ca) 17-21 Urotropin 10-12 Water Up to 1 l. The culture of the SIS is isolated. An example of water from the Caspian Sea. The composition is tested on seawater contaminated with SCB. A sample is taken in a sterile container, a certain amount of the composition is metered, kept for 2k hours at 20-22 C. Then 4–2 ml of the sample are taken and introduced into the Post Gate nutrient medium. In each case, 3 parallel experiments were conducted. Samples are placed in a thermostat and observed for 15 days. The results are presented in the table.
