Drilling and manufacturing device for oil shale true-triaxial hydraulic fracturing simulation experimental test blocks

The invention discloses a drilling and manufacturing device for oil shale true-triaxial hydraulic fracturing simulation experimental test blocks. The drilling and manufacturing device comprises a grouting pipe, left and right clamping devices, an oil shale drill pipe, an inner-threaded pressurizing casing, a pressurizing screw, and a tube twisting rotating plate. After the strength of a cement solidification test block is high, inner threads which are formed by sweeping in cement is matched with threads of the grouting pipe, a force generated by high-pressure liquid during a hydraulic fracturing experiment can be resisted, the bonding strength of the grouting pipe which is constructed in cement mortar in the traditional experiment can be achieved, and requirements of experiments are ensured. The grouting pipe is reserved in the test block, open holes with certain depth are drilled in oil shale by the oil shale drill pipe to form step-shaped holes, and casing assisting and open hole fracturing in production op
