Comprehensive experimental facility for breaking rocks with steel particle jet impact

The invention belongs to the field of oil drilling, and in particular relates to a comprehensive experimental facility for breaking rocks with steel particle jet impact. The comprehensive experimental facility comprises a water storage tank, a high-pressure pump, a high-pressure pipeline, a pressure gauge, high-pressure sphere tanks, an auger conveying device, a high-pressure valve, a test stand, a high-pressure experimental wellbore, rocks, a mortar pump, an injection type funnel, a hydraulic power unit, a hydraulic pipeline, a mass flow meter and a high-pressure diverting valve etc., wherein the auger conveying device can control the particle concentration of high-pressure water flow, the mass flow meter can be used for measuring and judging whether injection of steel particles is completed or not, the confining pressure of steel particle jet rock breaking can be regulated by a pressure regulating nozzle, and the two high-pressure sphere tanks work alternatively so that steel particles can be injected uninterruptedly into the high-pressure pipeline. The particles are delivered along with liquid, and the system drive is achieved by a hydraulic motor. The comprehensive experimental facility can be used for carrying out experimental analysis of the effect law of various parameters such as hydraulic power, lithological characters and jet on rock breaking efficiency, which provides theoretical guidance and equipment support for popularization and application of the technology of particle impact drilling.
