The invention discloses a communication method for a fire driven oil production air injection well and an oil production producing well. The communication method comprises the following steps that 1,target wells are determined in multiple production vertical shafts; 2, a well section located at oil deposit portion of a gas injection vertical well (5) is subjected to first oriented perforation, and the perforation direction of the first oriented perforation is that the the gas injection vertical well (5) is pointed at the target wells; 3, the position of the first oriented perforation of the gas injection vertical well (5) is subjected to first oriented fracturing, and the fracturing direction of the first oriented fracturing and the perforation direction of the first oriented perforationare the same; and 4, the first oriented fracturing position of the first oriented fracturing of the gas injection vertical well (5) is subjected to hydraulic fracturing. The communication method for the fire driven oil production air injection well and the oil production producing well can communicate with the air injection well and the oil production producing well, so that the overall effect offire driven oil extraction is greatly improved, and a thin interbedded and compact oil deposit fire driven extraction precedent is initiated.
