  • Patent number: 12085540
    Abstract: A rock true-triaxial testing system based on computerized tomography (CT) scanning aims to solve problems in the prior art, that is, the rigidity of the frame in the testing system is insufficient; high-pressure lines, wires, and signal lines are entangled when rotating; and the reaction frame and loading actuators obstruct the ray. The rock true-triaxial testing system includes a true-triaxial loading system and a high-energy accelerator-based CT scanning system, where the high-energy accelerator-based CT scanning system is located inside the true-triaxial loading system, and the high-energy accelerator-based CT scanning system is configured to image an internal structure of a cubic rock sample and continuously apply a stress to the cubic rock sample through a plurality of piston extension rods in the true-triaxial loading system. The rock true-triaxial testing system reduces radiation attenuation, and ensures imaging quality and a stable and smooth loading process.

  • Patent number: 11840914
    Abstract: A multi-stage perforation and shock wave combined device and method for initial fracture enhancement are provided. The multi-stage perforation and shock wave combined device for initial fracture enhancement includes a perforating gun and a shock wave excitation nipple, where the perforating gun is configured to fire perforating bullets into a formation to form initial fractures; the shock wave excitation nipple is connected to the perforating gun, and includes an energetic rod capable of exploding after excitation and a feeding assembly; the feeding assembly includes a pushing head, a reciprocating spring, and a feeding spring; and the reciprocating spring is configured to push the pushing head, so as to push a spare energetic rod into a target position.
