FIELD: oil and gas industry.
SUBSTANCE: invention refers to method for obtaining petroleum oil and involves separation of synoil obtained by Fischer-Tropsch synthesis so that there obtained is intermediate fraction having fraction content with boiling point of 150 to 360°C, not less than 90 wt %, and fraction content with boiling point of not less than 350°C, not more than 5 wt %, and paraffin component which is heavier than intermediate fraction, and bringing each of intermediate fraction and paraffin component into contact with hydrotreatment catalyst in presence of hydrogen, their mixing and separation so that petroleum oil can be obtained which has fraction content with boiling point of 150 to 360°C, not less than 86 wt % and fraction content with boiling point of not less than 350°C, not less than 5 wt %. Invention also refers to petroleum oil obtained as per this method.
EFFECT: oil has good low-temperature flow rate and kinematic viscosity, and high yield of oil.
