Problems solved by technology

In addition, as a high-energy-density rock-breaking tool, different parameters such as power and power density have different damage mechanisms for different rock samples. At the same time, different environmental parameters around the rock have different damage mechanisms for rock samples. The environmental parameters that have a greater impact on laser rock breaking are the rock bearing pressure and the temperature of the rock. However, the existing laser rock breaking experimental equipment cannot simulate the environmental parameters of the rock, thus affecting the accuracy of the laser rock breaking experiment. Provide more accurate data support for actual laser rock breaking, thus affecting the development of laser rock breaking technology

Abstract

The invention discloses an environment simulation device for laser rock breaking experiment, which comprises an experiment platform, a rock clamping simulation device, a laser generating device, a rock pressure loading system and a rock temperature simulation system, and the rock clamping simulation device is arranged on the experiment platform. The laser generating device is located directly above the rock clamping simulation device. The rock clamping simulation device includes five movable pressure bearing plates, which form a rectangular parallelepiped clamping chamber with an upper end opening, and the rectangular parallelepiped clamping chamber is used to clamp rocks. For the sample, five moving pressure bearing plates pressurize the rock sample in the cuboid clamping chamber by moving; the rock pressure loading system simulates the loading pressure of the rock, and the rock temperature simulation system simulates the ambient temperature of the rock sample. The environment of the rock sample is closer to the actual rock environment, thereby improving the accuracy of the laser rock breaking experiment, and submitting more accurate data support for the actual laser rock breaking.

Description

technical field [0001] The invention relates to the technical field of laser rock breaking, in particular to an environment simulation device for laser rock breaking experiments. Background technique [0002] The oil and gas resources in underground reserves are very rich. However, with the long-term mining, the development of underground mineral resources has gradually become deeper. Facing the characteristics of high ground stress, high rock hardness, and complex strata in deep strata, it is difficult for traditional drilling technology to effectively solve the problem. Drilling problems in deep complex formations. Laser rock breaking technology has also shown good application prospects in deep resource mining due to its advantages of low cost, high efficiency, and high reliability, and has become a research hotspot in recent years. In addition, as a high-energy-density rock-breaking tool, different parameters such as power and power density have different damage mechanis...
