The invention discloses a low yield oil field carbon dioxide flooding associated gas carbon dioxide recycling method, and belongs to the CO2 recycling method field. The low yield oil field carbon dioxide flooding associated gas carbon dioxide recycling method includes: collecting produced associated gas on a wellhead of an oil well; guiding the associated gas after being processed through a three-phase separator into a centralized processing station through an oil production pipeline; separating the associated gas in the centralized processing station by adopting a hollow fiber film separationmethod, and separating out CO2; and performing supercharging processing on the CO2 separated out, then delivering the CO2 to a CO2 injection station through an outward delivery pipeline, and afterwards conveying the CO2 from the CO2 injection station to the wellhead of the oil well so as to perform reinjection. By improving the prior art, the low yield oil field carbon dioxide flooding associatedgas carbon dioxide recycling method divides the associated gas produced from the wellhead of the oil well according to production stages, guides the associated gas into the centralized processing station through the oil production pipeline, supercharges the CO2 separated out through a hollow fiber film, delivers the CO2 to the CO2 injection station, then conveys the CO2 to the wellhead of the injection well so as to perform the reinjection, not only achieves recycling of the CO2 so as to reduce cost of air sources, but also can simultaneously improve recovery rate of crude oil, and finally realizes closed circulation and near-zero emission of the CO2.
