Injection production process of fluids produced by supercritical water oxidation

The invention relates to an injection production process of fluids produced by supercritical water oxidation fluids. The fuel is injected from the top of an evaporation wall reactor after being boosted to 22.1-30 MPa; the air is injected from the top of the reactor after being boosted to the same pressure and pre-heated to reach 300-500 DEG C. Evaporable water is injected from the side surface of the evaporation wall reactor in two branches after being boosted to the same pressure as the fuel; the initial temperature of the evaporable water in the upper branch after being pre-heated is 400-600 DEG C; the evaporable water in the lower branch is at normal temperature. After the supercritical water oxidation in the reactor starts, the evaporable water in the upper branch declines to 250-370 DEG C. The fluid in the reactor flows out from the outlet of the reactor and then is injected to the oil well through an injection pipe after being regulated to 5-30 MPa by a pressure regulating valve; and the evaporable water with the same pressure is injected to the annular space between the injection pipe and a shaft. According to the injection production process, the multiple hot fluids produced when the fuel is processed by the supercritical water oxidation are injected to the oil well, so that the viscosity of the thickened oil is reduced, the oil productivity is increased and the application prospect is wide.
