The invention relates to the mining industry and can be used to increase the extraction of oil, gas condensates and gas from deposits. What is claimed is a method for increasing the extraction of oil, gas condensates and gas from deposits and for ensuring the continuous operation of production and injection wells according to which working fluids are pumped into production and injection wells bored in deposits 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, wherein the working fluid used is a complex organic solvent with variable viscosity and density, and in order to treat the bottomhole zones of formations in the production wells and to kill the injection wells in order to displace oil from the formations in the direction of the production wells using said solvent, the density of the complex organic solvent is set at maximum and the viscosity of the solvent is set at minimum, while in order to kill production wells during repair with the concurrent treatment of the bottomhole zones of the formations, the density of the solvent is set at maximum. |
