Description

technical field [0001] The invention belongs to the field of geotechnical engineering tests, and in particular relates to a visual test system and a rock mass heating method. Background technique [0002] In the process of shale oil and gas exploitation, the geological body of the reservoir must be transformed to facilitate the exploitation of oil and gas resources. During the transformation process, it is hoped that more pores and fractures will be connected to each other, so that more oil and gas migration channels can be established, which is convenient for improving the exploitation of oil and gas resources. efficiency, however, the existing simulation tests for this type of research usually use the following heating methods when simulating the high temperature conditions of the rock mass: 1) put the pressure chamber in the mode of the temperature control facility, and use the temperature control equipment to make the instrument Placed in a high-temperature environment t...
