FIELD: oil and gas industry.
SUBSTANCE: declared invention relates to processing technique of wells and its bottom zones against sediments of iron sulphides, formed, particularly at corrosion of casing and oil-well tubing. In processing technique of wells by reagent for removing of iron sulphides in the capacity of reagent or removing of iron sulphides it is used reagent "ХПР-001", which is poured into hole annulus of well in amount, required for its location in well from dynamic head up to mouth, or it is pumped into well bottom zone. Invention is developed in dependent claim.
EFFECT: increasing of effectiveness and manufacturability of method, excluding of reagent pumping out necessity form the well.
