FIELD: oil and gas production.
SUBSTANCE: method includes arrangement of device with reagent in well bore or in tube side of surface oil field equipment, dissolution of reagent by produced fluid. Device used for supply of reagent is represented by container made of chambers serially joined at the ends with controlled primary dosing mechanisms installed in each chamber. Chambers via controlled secondary dosing mechanisms arranged in reservoir of preliminary mixing formed between controlled primary dosing mechanism and dead plug of chamber, are joined hydraulically to well or tube side.
EFFECT: efficient stable treatment of produced fluid, elimination of reagent loss.
