Abstract
FIELD: oil and gas production industry. SUBSTANCE: improved filtration properties of bottom-hole zone of reservoir are achieved due to preventing inflow of liquid into well during subsurface maintenance work which can reduce reduction of productivity of producing wells and injectivity of injection wells. During maintenance work according to method, injected into well is plugging liquid so as to prevent outburst of reservoir liquid and gas into atmosphere. Also performed are unsealing of well head and removal of plugging liquid from well after installing packer with non-return valve in well above reservoir level. Plugging liquid is injected above packer and by means of column of this liquid created is surplus pressure as against pressure occurred below packer. EFFECT: high efficiency.
