FIELD: oil and gas production industry, particularly to treat bottomhole formation zone during oil and gas production.
SUBSTANCE: method involves inserting material for further exothermal reaction performing in well; forcing hydrochloric acid through the material and executing time delay. The material used for exothermal reaction performing is in the form of aluminum cuttings. First of all aqueous carboxymethylcellulose solution is formed. Then calculated amount of aluminum cuttings and grinded raw rubber are added to the solution. Above components are taken in the following amounts (% by weight): carboxymethylcellulose - 1.5, aluminum cuttings - 14.5, raw rubber - 11.6, water - 72.4. After that the ready solution is forced in reservoir and 20% hydrochloric acid is injected in well. Ratio between aluminum and hydrochloric acid is 25.0 parts by weight of aluminum per 75.0 parts by weight of hydrochloric acid.
EFFECT: increased bottomhole formation zone treatment reliability.
