Particle jet flow and drill bit united casing pipe and rock drilling comprehensive experimental device

The invention belongs to the field of petroleum drilling and oil extraction and particularly relates to a particle jet flow and drill bit united casing pipe and rock drilling comprehensive experimental device. The comprehensive experimental device comprises a high-pressure pipeline, a hydraulic control rod, an electric lead screw, a drilling rod, a torque sensor, a rock, a casing pipe, a drill bit, a computer, a hydraulic control valve group, a guiding seat, a particle jet flow nozzle, a datum collector, a hydraulic working station, a load sensor, hydraulic jack, a speed-adjusting motor, a power transmitting assembly, a rotary speed sensor, a linear sensor and the like. The comprehensive experimental device can simulate drill bit rotating and adjust the rotary speed, the drilling pressure is exerted, and the size of the drilling pressure is adjusted; the drilling angle of the drilling bit is adjusted, and the rotary speed, the drilling pressure, the torque and the footage parameters of the drill bit are measured, stored and displayed in real time; the on-scene condition is well stimulated, hydraulic control and electric control are combined, the automatic degree and the integrated degree are high, the structure is reasonable, using is safe and reliable, and through an experiment, the particle jet flow and drill bit mechanical united casing pipe and rock drilling optimized parameters can be provided for on-scene construction.
