The deep rock three-dimensional seepage sealing structure comprises six sealing pressure heads and a hydraulic sealing system, and every two of the six sealing pressure heads are located in the X-axis direction, the Y-axis direction and the Z-axis direction; an annular sealing groove is formed in the front end of the sealing pressure head, and a sealing fluid injection channel communicated with the annular sealing groove at one end and connected with the hydraulic sealing system at the other end is arranged in the sealing pressure head; a cubic sample can be installed in the flexible inner cubic frame, the 12 outer edge angles of the flexible inner cubic frame are attached to the 12 inner edge angles of the rigid outer cubic frame, the front ends of the six sealing pressure heads stretch into the flexible inner cubic frame from six directions respectively, and the annular flanges are correspondingly inserted into the annular sealing grooves of the sealing pressure heads. Sealing fluid is injected into the ann
