Description

(54) РЕАГЕНТ ДЛЯ ПОДАВЛЕНИЯ РОСТА СУЛЬФАТВОССТЙНАВЛИВЙЮЩИХ БАКТЕРИЙ В ЗАВОДНЯЕМОМ НЕФТЯНОМ ПЛАСТЕ вращени  роста бактерий оценивали по степени подавлени  роста СВБ, которую определ ли по формуле: ( .уо JOO где Cj и С - содержание сероводорода в контрольной и исследуемой пробах (мг-л) соответственно. Испытани  проводили в трехкрат ной повторности на культурах анаэ ных СВБ, содержащихс  в пластовой воде нефтепромыслов. В таблице приведены результаты определени  степени подавлени  СВБ при соответствукндих концентраци х алкилсульфината меди. Дл  сопоставлени  там же приведены результаты, полученные в аналогичных услови х с применением акролеина по известному способу.(54) REAGENT TO SUPPRESS THE GROWTH OF SULPHATIC STEEL BULKING BACTERIA IN THE PLANTED OIL PLATE OF Bacteria Growth Rotation was assessed by the degree of reduction in the growth of sulfate reducing bacteria, which was determined by the formula: (.you JOO where Cj and C are the hydrogen sulfide content in the test group, which is a test group that studies samples, and CJ and C are the hydrogen sulfide growth control, which was determined by the formula, (Cу and C is the content of hydrogen sulfide in the test group, which is a test group that studies a test group), which is determined by the formula: The tests were carried out in triplicate on cultures of ana- nated SSC contained in oil fields, the table shows the results of the determination of the reduction of SSC at the corresponding concentrations of copper alkylsulfinate. For comparison, the results obtained under similar conditions with the use of acrolein by a known method are also shown there.

Представленные данные показывают, что предлагаемый способ обеспечивает высокую степень подавлени  СВБ. Так, при концентрации 0,001% алкилсульфинат обеспечивает степень подавлени  95% и вьаые, в то врем  как в иэвес ном способе эти результаты достигаютс  при концентрации акролеина выше 0,1%. Основными преимуществами предла. гаемого способа  вл ютс : .высока  эффективность подавлени  сульфатвосстанавливах дих бактерий; возможность охраны окружающей среды, так как .предотвращение ijpcTa. сульфатвосстанавливакцих бактерий позволит снизит заражение нефт ных месторождейий .и добываемой продукции сероводород  л, Предотвратить сероводородную и микро биологическую коррозию нефтепромысло вого оборудовани , тем самым сократить чиЬло аварийных порывов водоеодов и т.д.; расширение ассортимента химических продуктов, используемых дл  предотвращени  роста сульфатвосстанавливающих бактерий/ что весьма важно, так как микроорганизмы обладают способностью адаптироватьс ; высока  технологичность способа, так как примен емый бактерицид не токсичен , не взрыво- и пожароопасен. Формула, изобретени  Приме1)ёние алкилсульфината меди формулы: (R-SOj,)2Cu, где R - алифатический радикал, от ;i в качестве реагента дл  подавлени  роста сульфатвосстанавливдащих бактерий в эаводй еМом нефт ном пласте. Источники информации, прин тые во внимание при экспертизе I. Патент ОНА 2987475, . кл. 255-8.55, опублик. 1961.The data presented show that the proposed method provides a high degree of reduction of SSC. Thus, at a concentration of 0.001%, the alkyl sulfinate provides a degree of inhibition of 95% and severe, while in the iSnual method, these results are achieved with an acrolein concentration higher than 0.1%. The main advantages of the offer. The desired methods are: high suppression of sulfate reduction of bacteria; the possibility of environmental protection, as .preventing ijpcTa. sulphate-reducing bacteria will reduce the contamination of oil fields and the production of hydrogen sulphide, prevent the hydrogen sulphide and micro biological corrosion of oil-field equipment, thereby reducing the number of emergency water gusts, etc .; expanding the range of chemical products used to prevent the growth of sulfate-reducing bacteria / which is very important, since microorganisms have the ability to adapt; the processability of the method is high, since the bactericide used is non-toxic, non-explosive and fire-hazardous. Formula of the Invention Example 1) A copper alkyl sulphinate formula of the formula: (R-SOj,) 2Cu, where R is an aliphatic radical, from; i as a reagent for suppressing the growth of sulphate-reducing bacteria in an e-oil formation.
