FIELD: oil production, particularly methods to supply reagents having different consistence, composition and target.
SUBSTANCE: method involves determining water content in product to be produced, well production; determining well problems, namely presence of asphalt-tar-paraffin deposits or salt deposits in wells, corrosion, highly-viscous emulsion formation; arranging device filled with reagent in well; solving reagent with produced liquid flow passing through means hydraulically connected with well interior through orifices. Device is made as container including chambers serially connected one to another by ends thereof. Reagent of one or several types is placed in each chamber. Upper and lower chamber ends are closed. The chambers are connected one to another by flexible connection. The orifices are arranged at 30°-150° angle to longitudinal chamber axis and are created in fixed chamber part in dependence of reagent type, well output and particular well problem. Rate between summary cross-section of orifices formed along chamber length equal to 1 m and chamber cross-sectional area is 0.01-5.
EFFECT: possibility to use the device in wells having different outputs, at different operational regimes and with formation fluid having any viscosity.
