FIELD: oil production industry, particularly to supply chemical reagents into well or pipeline.
SUBSTANCE: method involves connecting pressure source, namely gas, and chemical reagent vessel with object to be treated; injecting chemical reagent into the object without shutdown thereof or performing technological pause and bringing the object into operation. Hole annuity or land-based pipeline are used as the object to be treated. Pressure source is hole annuity of production well. Gas is accumulated in above hole annuity by closing gate valve of wellhead fittings, which result in pressure increase up to value exceeding that in well to be treated or in pipeline for not less than 0.2 MPa.
EFFECT: increased efficiency of chemical reagent injection into object to be treated.
