FIELD: oil extractive industry.
SUBSTANCE: inter-pipe space of well is filled with anti-corrosion liquid and said liquid is pressed into well-adjacent space and into pit-face area of well along inter-tubular space. Technological delay, discharge and creation of pressure is performed along inter-tubular space. During well operation inter-tubular space is used as reservoir for storing and using anti-corrosion liquid. Anti-corrosion liquid is gradually fed from inter-tubular space into well-adjacent space and into pit-face area. As anti-corrosion liquid compound on basis of phosphate diammonium is used.
EFFECT: higher efficiency.
