FIELD: oil and gas industry.

SUBSTANCE: invention refers to oil and gas industry, namely to utilisation and processing methods for associated and natural gas with high methane homologue content to obtain oil products. Processing method for natural and associated gas with high content of heavy methane homologues by selective oxidation of hydrocarbon gas and further carbonylation of products obtained involves mixing of hydrocarbon gas with oxygen or oxygen-containing gas at molar ratio of heavy carbon components to oxygen 5÷0.2:1, and selective oxidation of heavy components at air or near-air pressure and temperature of 500-800°C, and products obtained are processed in the presence of carbonylation catalysts containing compounds of VIII group metals and phosphine (arsinic) ligands, at 80-120°C and air pressure to obtain liquid products such as aldehydes, carbonic acids, diethyl ketone, polyketones, and dry fuel gas saturated with methane and purified from heavy components.

EFFECT: solution to the problem of associated oil gas utilisation, common to all oil companies.
