The invention provides a selective sealing method of a water logging oil reservoir fire flooding production well. Selective sealing is conducted on the water logging oil reservoir fire flooding production well by means of papermaking black liquid, and the method specifically includes the steps of adjusting the total solid content of the papermaking black liquid to be 0.8-2%, adding 1-2 wt% of sodium oxalate to be injected into a stratum, and stopping construction when the stable squeezing pressure is increased by 2-5 MPa or the maximum pressure reaches 8-10 MPa. Papermaking black liquid wasteis used, safety and environment protection are achieved, water control and sealing are equally important, the targeted property is high, and an effective sealing effect can be achieved in the stratum;harmful oxygen and acidic gases in the stratum can be effectively reduced, the fire flooding swept volume can be increased, and the existing pipe column construction operation is simple.
