MODULAR INSTALLATION FOR PROCESSING FLOW OF COMPOSITION OF REVERSE INFLOW AND METHODS FOR PROCESSING IT Russian patent published in 2019 - IPC E21B21/06 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions relates to treatment of a flow of a composition of reverse inflow from the mouth of an oil and gas producing well. Method according to first version includes reception of flow of reverse inflow composition from wellhead, wherein flow of reverse inflow composition has a first flow rate and a first pressure, controlling a first flow rate to achieve a second flow rate by controlling flow of the composition of the reverse inflow to achieve a second pressure, which differs from the first pressure, supplying the flow of reverse inflow composition to the separator, separating the flow of reverse inflow composition into the first gas flow and the condensed flow, controlling first gas flow to third pressure and third flow rate, supplying the condensed flow to the degasifier, removing carbon dioxide-rich gas from the condensed flow, compressing the carbon dioxide-rich gas until the first gas flow third pressure is achieved, mixing carbon dioxide-rich gas with a first gas flow to form a second gas flow having a third flow rate and a third pressure, feeding the second gas flow into the flow regulator and controlling the third flow rate of the second gas flow by adjusting the third pressure of the second gas flow until a fourth pressure is obtained, which differs from the third pressure.

EFFECT: providing modular organization of gas extraction, possibility of repeated use of flow components and recirculation, providing anhydrous technology.
