Description
Hfcjx услови х ввод т изученные состабы в соответствующих конр,ентраии х и выдерживают 24 ч лри 32°С. ЭГатем из этих проб. отбирают по .1 мл жидкости и ввод т в бутылочки с питательной средой гГостгейта. Бутылочки термостатируют при 32С в течение. 15 сут. Одновременно став т контрольные без добав.ки I.бактерицидного состава.The Hfcjx conditions are introduced by the studied compounds into the corresponding concentrations, and they are kept for 24 hours at 32 ° C. EGATEM from these samples. take .1 ml of liquid and injected into bottles of Gg gategate. Bottles thermostatic at 32C for. 15 days At the same time put the control without the addition of I. bactericidal composition.
Эффективность предотвращени роста бактерий оценивают по степени подавлени бактерий.The effectiveness of preventing the growth of bacteria is assessed by the degree of bacterial inhibition.

0,1 Из таблицы видно, что предлагаемый способ обеспечивает высокую сте пень подавлени СВБ,. Основные преимуцест§а предлагаем го способа: 1. Высока эффективность,так как полное подавление роста бактерий обе печиваетс при низких концентраци х добавл емых компонентов к закачивае мой воде. 2.Расширение ассортимента доступных к. промышленному применению химических продуктов, используемых дл предотвращени роста бактерий, Это обсто тельство вл етс важным так как микроорганизмы способны ада тироватьс и требуют периодического применени различных по механизму действи .бактерицидов, 3.Предотвращение сероводородной и микробиологической коррозии нефтепромыслового оборудовани , со кращение числа аварийных порывов. водоводов и снижение экономических затрат. 4.Повышение приемистости скважин , возможность увеличени нефтеотдачи пластов в. месторождени х. вступивших в позднюю стадию эксплуатации . 5. Возможность охраны окружающей среды, так как эффективное предотвращение роста СВ позволит снизить заражение нефт ных месторождений и добываемой продукции скважин сероводородом. Фо$)мула изобретени , 1.Способ предотвращени роста бактерий при заводнении путем добавКи в заканчиваемую воду химических реагентов, отличающи йс тем, что, с целью повышени степени предотвращени роста бактерий, в качестве химического реаген а используют 2-метилфуран. 2.Способ по п. 1, отличающийс тем, что 2-метилфуран ввод т в количестве 0,0025-0,1 мас.%. Источники информации, прин тые во внимание при экспертизе 1,Авторское свидетельсвто СССР № 449146, кл. Е 21 В 43/22, 1974. 2.Патент США 2987476, кл. 2528 .55.0.1 From the table it can be seen that the proposed method provides a high degree of suppression of SSC ,. The main advantages of the proposed method are: 1. High efficiency, since the complete inhibition of bacterial growth is both baked at low concentrations of the added components to the injected water. 2. Expansion of the range of chemical products available to industrial use. These products are used to prevent the growth of bacteria. This is important because microorganisms are capable of adhering to and require periodic use of bactericides of different mechanism of action. 3. Prevention of hydrogen sulfide and microbiological corrosion of oil field equipment. reducing the number of crashes. water pipelines and reduced economic costs. 4. Increasing the injectivity of the wells, the possibility of enhanced oil recovery in. fields. entered the late stage of operation. 5. The ability to protect the environment, as effective prevention of the growth of oil-borne deposits will reduce the contamination of oil fields and the production of wells with hydrogen sulfide. An inventive formula, 1. A method for preventing the growth of bacteria by flooding by adding chemical reagents to the finished water, characterized in that, in order to increase the degree of prevention of the growth of bacteria, 2-methylfuran is used as a chemical reagent. 2. A process according to claim 1, characterized in that 2-methylfuran is introduced in an amount of 0.0025-0.1 wt.%.
