The utility model relates to an oil-containing solid oil washing system. According to the technical scheme, an oil washing medium is tap water or seawater, the lower side of a dissolving oil washing system is connected with a heating system, the top of the dissolving oil washing system is connected to a low-temperature constant-temperature cooling system through a pipeline, and the dissolving oilwashing system is provided with a pumping system and a back pressure system; tap water is heated to supercritical water through the heating system and then pumped to the dissolving and oil-washing system, oil-containing sludge in the dissolving and oil-washing system is soaked and dissolved, oil in oil-containing solid is extracted to form a supercritical water solution of oil, and then the supercritical water solution is pumped to the low-temperature constant-temperature cooling system to be cooled and then fed to the oil-water separation system to achieve layered separation. The oil recoverydevice has the advantages
