The invention relates to a high-frequency vibrating impact rock-breaking experiment device, which comprises a main machine, a pump station, a control console and a data collection system, wherein high-frequency vibrating impact excitation required for breaking rocks is simulated through coordination of an axial high-frequency vibrating drill and a horizontally rotating rock sample; the main machine comprises a frame and a hydraulic cylinder; a force sensor is arranged on the lower part of the hydraulic cylinder; the lower part of the hydraulic cylinder is connected with return mass; the return mass is connected with an exciter; a spiral spring is arranged between the exciter and the drill; the lower part of the spiral spring is connected with a vibration sensor; an accelerometer is arranged between the spiral spring and the vibration sensor; a linear variable differential transformer is arranged on the spiral spring; a rotary table is arranged below the drill; a rock sample is arranged on the rotary table; the rotary table is arranged on a lifting seat; a rotary sensor is arranged on the rotary table; and the force sensor, the vibration sensor, the accelerometer, the linear variable differential transformer and the rotary sensor are all connected with a data collection system. According to the high-frequency vibrating impact rock-breaking experiment device, the current situation that a still rock sample is broken by virtue of the drill in the prior art is broken through; and novel high-frequency vibrating impact rock-breaking device and novel high-frequency vibrating impact rock-breaking method are created.
Description
technical field [0001] The invention relates to a drilling device used in the field of petroleum and natural gas engineering for generating high-frequency vibration impacts to break rocks and capable of measuring the resonance frequency of rocks, in particular to a high-frequency vibration impact rock breaking experiment device. Background technique [0002] With the increase of drilling depth and the increasing difficulty of rock breaking, conventional drilling technologies such as rotary drilling with drill bit and water jet can no longer meet the needs of modern drilling operations. New drilling methods, such as resonance drilling technology and harmonic vibration excitation drilling technology etc. New drilling equipment, such as torsion impactors, axial hydraulic impactors and other equipment, have become the focus of today's research and invention. These new technologies and new equipment have a common feature, which is to use the principle of high-frequency vibration ...
