| titleOfInvention | Coal rock sample for hydraulic fracturing experiment and manufacturing method thereof |
| abstract | The invention relates to a coal rock sample for a hydraulic fracturing experiment, which is a cube structure formed by layering and pressing coal powder and gangue powder, wherein: coal dust layer and coal gangue layer appear in turn, can adjust the thickness of coal dust layer and coal gangue layer according to experiment purpose and requirement, set up the round hole in the vertical downwards in coal petrography sample square top surface center, install the pipe nipple joint in the round hole, the evenly symmetric slot that distributes in pipe nipple joint bottom, the hole between pipe nipple joint and the round hole adopts sealed glue to fill, the pipe nipple joint firmly bonds together with the round hole, adapter is installed at pipe nipple joint top. The invention has wide application range and can be used for pressing coal and rock samples in cubes, cuboids, cylinders and other shapes; the principle is concise and clear, the operability is strong, the coal rock structure and physical property parameters can be accurately controlled, and the batch production is easy. |
