METHOD OF CONTROL OF CORROSION CAUSED WITH SULPHATE-REDUCING BACTERIA

摘要

FIELD: oil and gas production.;SUBSTANCE: invention refers to oil industry and can be implemented for inhibition of growth of sulphate-reducing bacteria and inhibition of corrosion in systems of collection and treating of oil. The method of control of corrosion caused with sulphate reducing bacteria consists in pumping volume of solution of bactericide into annular space of an operating oil well at the outlet of which there is detected corrosion of pipes caused with sulphate-reducing bacteria. As solution of bactericide there is used mixture of bactericide SNPH-1004 and surface active substances ML-81B at ratio correspondingly (0.9-1.1):(0.9-1.1) by weight in form of 1.8-2.2 % water solution in water with density not more 1.07 g/cm³.;EFFECT: enhanced efficiency of anticorrosive protection at wells with initiated corrosion.;3 ex
