FIELD: chemistry.
SUBSTANCE: invention relates to electrochemical protection of underground structures against ground corrosion and can be used in oil and gas industry, as well as in municipal services when performing anode earthing of deep-lying in systems of electrochemical protection of main pipelines and other underground metal structures from corrosion. Method includes drilling of well, installation in pipe of current conducting composite pipes, placement in tubes of protective electrodes with output of connecting cable and filling of tube with current-conducting gel, wherein before drilling well vertical electrical probing of installation place, according to the results, anode grounding section is divided into intervals characterized by different specific electric resistance of soil, pipes are selected from current-conducting composite with specific electric resistance corresponding to each interval, and installed in well in appropriate interval so that pipes with lower electric resistance after installation were in soil with high electric resistance.
EFFECT: technical result consists in simplification of installation of bottom anode earthing, maintenance of its repairability, as well as higher efficiency of its operation due to the installation of electrodes in current conducting pipes with different specific electric resistance, which is selected taking into account the electrical resistance of soil layers.
