description The invention discloses a linear well pattern fireflood oil well production state recognition method. The recognition method comprises the following steps that the acid value of oil produced by a production well and the CO2 content of tail gas are collected; carrying out interval division on the acid value of the produced oil and the CO2 content of the tail gas; establishing a two-dimensional rectangular coordinate system, displaying a produced oleic acid value in a horizontal coordinate, displaying the CO2 content of the tail gas in a vertical coordinate, and drawing a cross plot according to an interval division result; calculating to obtain a fireflood oil well production gas-liquid ratio; marking the production gas-liquid ratio in the cross plot; the production state reflected by each mark is analyzed, and corresponding regulation and control measures are recommended; establishing a double-coordinate system fireflood oil well production state rapid identification chart based on the produced oleic acid val
