METHOD FOR UTILIZATION OF ASSOCIATED PETROLEUM GASES IN THE FIELDS Russian patent published in 2022 - IPC E21B41/00 E21B43/34 E21B43/40 

FIELD: oil industry.

SUBSTANCE: invention relates to equipment for the arrangement of an oil field. A method for utilization of associated petroleum gases is proposed, in which the first and second transported process modules are connected to the process line and the associated petroleum gases are burned in the electric generator set of the first module with an enriched or stoichiometric mixture. Next, oxygen-free flue gases are fed to the condensing heat exchanger of the second process module to cool the gas mixture to a temperature below the dew point and separate water in the form of a liquid phase. Then the resulting chemically neutral mixture, consisting mainly of carbon dioxide and nitrogen, is sent to the compressor station of the second process module and then the said chemically neutral mixture is pumped into the oil reservoir.

EFFECT: improving the environmental situation by eliminating flaring and creating a unified transportable module for processing and disposal of flue gases, as well as improving the safety and prevention of acidification of petroleum products in the reservoir by pumping an oxygen-free gas mixture into the well.
