The invention relates to the mining industry and can be used to increase hydrocarbon extraction. The technical result is that of displacing hydrocarbons without leaving portions of formations untreated, ensuring the continuous operation of wells, displacing formation water from gas-bearing formations, reducing the flooding of same, and preventing the mass discharge of rock particles into well bottoms, which causes rock jams and the failure of downhole equipment. In the method for increasing the extraction of oil, gas condensates and gas from deposits and for ensuring the continuous operation of production and injection wells, working fluids are pumped into production and injection wells in order to treat the bottomhole zones and to displace oil from the formations, the wells are repaired and the pipes and the equipment disposed therein are subjected to anti-corrosion treatment and, in the event of low surface temperatures, the pipes in the upper parts of the production wells are cleaned of asphalt, tar and paraffin deposits. The working fluid used is a complex organic solvent with variable viscosity and density. |
