Mechanical rock-breaking experiment device and method

Abstract

The invention relates to a mechanical rock-breaking experiment device and a mechanical rock-breaking experiment method. A main machine frame of the mechanical rock-breaking experiment device is formed by arranging two upright columns between a transverse beam and a base; a lifting platform is arranged between the two upright columns and is slidably connected with the upright columns; a cross-shaped sliding platform is arranged on the lifting platform; a four-claw chuck is mounted on the cross-shaped sliding platform; a rock sample is fixed on the four-claw chuck; the cross-shaped sliding platform is connected with a motor; a displacement sensor is arranged between the lifting platform and the transverse beam; a piston rod of a hydraulic oil cylinder penetrates out of the base; the upper end of the piston rod of the hydraulic oil cylinder is connected with a load sensor and props the bottom of the cross-shaped sliding platform; a hydraulic motor is connected with a hydraulic pump and respectively connected with a tacho-torquemeter and a drill rod through couplers; the displacement sensor, the load sensor and the tacho-torquemeter are all connected with a data acquisition system; the data acquisition system is connected with a computer; a control system is mounted in the computer. The high-drill-pressure and high-torque full-size cutting tooth rock-breaking process, the rock abrasive property testing process and the micro-drill-bit rock-breaking process can be simulated, and the drilling performance and the quality of a drill bit are determined and evaluated.

Description

technical field [0001] The invention relates to a cutting rock-breaking simulation device mainly used in the fields of rock mechanics engineering, petroleum engineering, mining engineering and the like, in particular to a mechanical rock-breaking experimental device and an experimental method. Background technique [0002] Petroleum is not only a common commodity in people's daily life, but also an extremely important strategic resource. In recent years, the state has promulgated relevant policies and regulations, which will vigorously promote deep and peripheral prospecting. Drilling is an irreplaceable technical means in deep geological prospecting, and the research on the mechanism of rock fragmentation is one of the important basic theoretical research directions of drilling, which has been in the exploration stage so far. In order to gain a deep understanding of the internal mechanism of the drill bit breaking rock and improve the ability to artificially control the ro...
