Description

венно до 70% окислов железа и до 90% сульфидов железа, после диспергировани  обрабатывают 100 мл водного раствора, содержаш:его 90 гр/литр гидразина сол нокислого , 10 гр/литр триполифосфата натри  при температуре . Осадки обрабатывают в течение 30 минут в услови х статистического растворени  в термостате с иоследующим пропуском полученного раствора через фильтр. Содержание железа в фильтрате определ ют колориметрическим методом с помощью сульфосалициловой кислоты . Степень растворени  соединений железа данным раствором при температуре , определ ема  как отношение количества растворенного железа к общему количеству железа в образце, составила 0,72 дл  осадков , содержащих окислы железа, и 0,65 дл  осадков, содержащих сульфиды.70% of iron oxides and up to 90% of iron sulfides, after dispersion, are treated with 100 ml of an aqueous solution, containing: its 90 g / liter of hydrazine hydrochloride, 10 g / liter of sodium tripolyphosphate at a temperature. The precipitates are treated for 30 minutes under conditions of statistical dissolution in a thermostat followed by passing the resulting solution through a filter. The iron content in the filtrate is determined by a colorimetric method using sulfosalicylic acid. The degree of dissolution of the iron compounds by this solution at a temperature, defined as the ratio of the amount of dissolved iron to the total amount of iron in the sample, was 0.72 for precipitates containing iron oxides and 0.65 for precipitates containing sulfides.

Применение предлагаемого способа, таким образом, позвол ет увеличить степень растворени  железа и, соответственно, повысить эффект обработки скважин на 88- 100% (за счет повышени  степени растворени  с 0,41 до 0,82) дл  осадков, содержащих окислы железа, и на 18-30% (повышение степени растворени  от 0,60 до 0,80) дл  сульфидных осадков.The application of the proposed method thus allows an increase in the degree of dissolution of iron and, accordingly, increases the effect of well treatment by 88-100% (by increasing the degree of dissolution from 0.41 to 0.82) for sediments containing iron oxides, and 18-30% (increase in dissolution from 0.60 to 0.80) for sulfide precipitates.

Кроме того, применение предлагаемого способа позвол ет увеличить межремонтный период эксплуатации скважин, что дает дополнительный экономический эффект.In addition, the application of the proposed method allows to increase the period between repairs of wells, which gives an additional economic effect.
