Description
Изобретение относитс к нефтедобывающей промьлиленности, в частности к эксплуатации нефт ных месторождений с применением заводнени водами различного состава, привод щими кпо влению сероводорода в добываемой продукции. Известен способ борьбы с образова нием сероводорода путем закачки в пласт насыщенных растворов хлористог натри l . Недостатком способа вл етс способность многих.штаммов сульфатовосстанавливающих микроорганизмов к ада тации и успешному развитию, что способствует образованию сероводорода. Цель изобретени - предотвращение образовани сероводорода в заводн емом нефт ном пласте. Это достигаетс тем, что в качест ее реагента дл предотвращени образовани сероводорода примен ют хлоргидрат аминопарафина, который представл ет собой смесь соединений общей формулы: CHj(CHj-)-CH-(CH2) NH2 Хлоргидрат аминопарафина получают нитрованием парафинов нефти с последующими гидрированием и обработкой сол ной кислотой и примен ют в народном хоз йстве в качестве флотореагента , деэмульгатора и ингибитора коррозии . Б таблице приведены результаты испытаний реагента. Из сильноминерализованной (d-1/ll г/см) сточной воды нефтепромыслов Башкирии была выделена культура сульфатвосстанавливающих бактерий на модифицированной питательной среде Постгейта, содержащей лактат натри , дрожжевой экстракт и минеральные соли. Пресную воду освобождали от кислорода продувкой азотом, заражали культурой бактерий. Один из опытов был контрольным (без добавки реагента), в другие добавл лось от 25 до 300 мг/л хлоргидрата аминопарафина. После суточной выдержки проба воды высевалась на питательную среду, термостатировалась в течении 10 сут при 35°С, затем в среде определ лась концентраци сероводорода. Применение указанного реагента дл борьбы с образованием сероводорода в заводн емых нефт ных пластах имеет преимущества по сравнению с npHMeHOHHeNT хлористого натри , так как реагент эффективен по отношению .к штамм,зм мнкроорганизмов , адаптировавшихс в сильноминерализованных водных средах, закагчиваемых в нефт ные пласты. Кроме того, вследствие меньших дозировок, сокраадаютсй затратына обработку закачиДозировка реагента, мг/л VThe invention relates to oil production, in particular, to the exploitation of oil fields with the use of water flooding with waters of different composition, leading to the growth of hydrogen sulfide in the products produced. The known method of combating the formation of hydrogen sulfide by pumping saturated solutions of sodium chloride l into the formation. The disadvantage of this method is the ability of many strains of sulfate-reducing microorganisms to adat and successful development, which contributes to the formation of hydrogen sulfide. The purpose of the invention is to prevent the formation of hydrogen sulfide in a waxy oil reservoir. This is achieved by using aminoparaffin hydrochloride as a reagent to prevent the formation of hydrogen sulfide, which is a mixture of compounds of the general formula: CHj (CHj -) - CH- (CH2) NH2 The aminoparaff hydrochloride is obtained by nitration of oil paraffins, followed by hydrogenation and treatment hydrochloric acid and is used in the national economy as a flotation reagent, demulsifier and corrosion inhibitor. B table shows the results of the test reagent. From the highly mineralized (d-1 / ll g / cm) wastewater from the oil fields of Bashkiria, a culture of sulfate-reducing bacteria was isolated on Postgate modified nutrient medium containing sodium lactate, yeast extract and mineral salts. Fresh water was freed from oxygen by purging with nitrogen and contaminated with a bacteria culture. One of the experiments was a control (without the addition of a reagent), from 25 to 300 mg / l of aminoparaffin hydrochloride was added to the others. After daily incubation, the water sample was sown on a nutrient medium, thermostatically controlled for 10 days at 35 ° C, then the concentration of hydrogen sulfide was determined in the medium. The use of this reagent to combat the formation of hydrogen sulfide in watered oil formations has advantages over sodium chloride npHMeHOHHENT, since the reagent is effective in relation to the strain, the microorganisms adapted to highly mineralized aquatic environments, which are hardened into oil reservoirs. In addition, due to the lower dosages, the processing costs are reduced; Reagent dosage, mg / l V
