FIELD: oil and gas production, particularly inhibition of corrosion, paraffin and salt deposition and sulfate-reducing bacteria growth in boreholes or wells.
SUBSTANCE: method involves metered supplying chemical reagents of different types simultaneously or serially for different predetermined depths in dependence of production and technical conditions of well operation. Chemical reagents are supplied through capillary hose including capillary pipes, protective cushion and shell. Chemical reagent flow regulation is performed by metering electric plant at well head.
EFFECT: increased efficiency of downhole equipment protection due to provision of free metered chemical reagent supplying for necessary depth during pumping equipment operation.
