Experimental apparatus and experimental method for physical modeling of fluid migration and accumulation process with contemporaneous structural deformation

An experimental apparatus for physical modeling of a fluid migration and accumulation process with contemporaneous structural deformation, comprising a structural deformation experiment box, a structural deformation control device and a fluid control device;

• wherein the structural deformation experiment box is installed in a basket experiment module (21) on a cantilever of a drum centrifuge;
• the structural deformation control device comprises a hydraulically driven triangular push plate (11) moving in vertical and horizontal directions;
• and the fluid control device comprises fluid cylinders (27) filled with fluids or plastic materials;
• wherein the fluid control device further comprises a fluid injection lifting device (25), a pressure column (26) and an injection pipe (29);
• the fluid cylinders (27) are connected with an injection port (24) on a frame (16) of the structural deformation experiment box through the injection pipe (29).
