    The process is of special interest to refinieries in the neighbourhood of existing oilfields. The crude oil additionally released in the known manner by the introduction of hot water or steam contains also a so-called petroleum gas consisting largely of methane as well as other combustible gases. According to the invention, this gas is converted in hydrogen using a cracking oven heated by a high-temperature reactor, with steam being produced by the heat released by the cracking oven

    The invention relates to a method for producing tertiary oil using getter oil gas and can be applied in refineries located adjacent to existing oil fields.
    The known method of oil production, including oil production, steam injection into the oil field, the splitting of methane into hydrogen and carbon monoxide.
    The disadvantage of this method is that the hydrogen obtained from the splitting of methane cannot be used at a refinery.
    The closest to the proposed technical essence is the oil extraction process, which includes extraction of fluid through the production well, separation of fluid into oil, gas and water, steam generation using heat from a helium-cooled high-temperature reactor, use of steam for injection into the oil field, and the other part is to be supplied to the heat turbine, which drives the electric generator.
    However, the known method does not provide for the simultaneous production of steam and hydrogen.
    The purpose of the invention is to increase the efficiency of the process by simultaneously producing steam and hydrogen.

    The drawing shows schematically the technological scheme of the method.
    In the oil field 1 with a large number of deep wells, a steam line 2 is laid, while the adjacent outlet pipe 3 feeds up a mixture of oil, water and gas dissolved in oil to a gas separator A, from which a mixture of oil and water is conducted to a water separator 5, while the gas after passing the desulfurizing device 6 and the separator 7 through the heater 8 with admixture of water vapor is passed into the reaction furnace 9. The gas split there when supplied with heat is cooled first in the heater 8, and then in the steam generator 10, in the converting device 11, the gas-containing carbon monoxide with steam is converted to carbon dioxide and hydrogen, the gas mixture leaving there in the gas scrubber 12 is freed from carbon dioxide and in the low-temperature gas separation device 13 from methane and other carbon-containing gases, which are again fed into the gas stream downstream of the separator 7. The heat of high temperature required for the reaction furnace 9 is supplied by a high-temperature gas-cooled reactor 14 through closed helium circuit 15, which, after leaving the reaction furnace 9, heats another steam generator 16 and from the gas blower 17 again leads to the reactor 14.
    The steam heated in the steam generator 16 via the steam line 2 can be used directly to heat the oil field, it is advisable to turn on the steam converter 18 between them, so that plant components that impose high demands on water quality can be loaded with thoroughly prepared feed water, while steam supplied to the oil field is more
    poor quality can be taken with the help of the feed pump 19 from the water preparation device 20, which again uses the forced out of
    water separation device 5 water. Depending on the required quantities, pressures and temperatures, the quantities of steam required for the process can be partially taken directly from the steam generators.
    10 and 16 or after the operation in the first turbine 21. In addition, the device 22 is indicated for supplying water, which serves as a compensation for the extraction of steam in the mixer 23, which is not introduced into the circulation loop anymore. In the separator 7, high-quality hydrocarbons (more than C) are separated and supplied for special treatment.

    Invention Formula
    A method of tertiary oil production, which includes production of fluid through a production well, separation of fluid into oil, gas and water, steam generation using heat from a helium-cooled high-temperature reactor, use of steam for injection into the oil field and another portion for heat turbine, which drives an electric generator that differs
    so that, in order to increase the efficiency of the process by simultaneously producing steam and hydrogen, the separated gas is purified, desulfurized, freed from heavy hydrocarbons, methane is obtained from gas, mixed with steam, this mixture of methane and steam is split into hydrogen and carbon monoxide, obtained after decomposition, the mixture is cooled in the steam generator, by conversion
    carbon monoxide with steam is converted into carbon dioxide and hydrogen, carbon dioxide is separated from hydrogen, and not split methane and other hydrocarbons are fed into the gas stream to be split.
