COMPLEX 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 oilfield. A complex for the utilization of associated petroleum gases in the fields is proposed, containing the first technological module and the second technological module connected to the production line. At the same time, the first technological module contains a gas electric generator unit operating on associated gases of the field with an enriched or stoichiometric mixture, and the second technological module contains a condensing heat exchanger and a compressor station. Moreover, the condensing heat exchanger is made with the possibility of connecting to the outlet of oxygen-free flue gases of a gas electric generator set and its output is connected to the aforementioned compressor station. The compressor station is designed with the possibility of supplying a compressed chemically neutral mixture consisting mainly of carbon dioxide and nitrogen for its injection into the oil reservoir. At the same time, each technological module contains a load-bearing structure designed to accommodate equipment so that each module is made in the form of one cargo unit.

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 safety and preventing acidification of petroleum products in the reservoir by pumping an oxygen-free gas mixture into the well.
