Abstract

The invention discloses a high-temperature fractured rock mass permeation test device and a high-temperature fractured rock mass permeation test method and relates to a rock mass mechanical test technology. In the device, a displacement control system (30), an upstream pressure control system (10) and a downstream pressure control system (40) are connected with a high-temperature permeation test tank (20) respectively so as to realize control over the high-temperature permeation test tank (20); and the upstream pressure control system (10), the downstream pressure control system (40) and the high-temperature permeation test tank (20) are connected with a data acquisition system (50) respectively to realize date acquisition. The device and the method are suitable for tests of water and airpermeation of various fractured rock masses, and the permeability coefficient of the rock masses can be measured; and the measurement of permeability coefficients of fractures in the fields of hot dry rock geothermal exploitation, deep shale gas exploitation and artificial induction fracture application and the like can be simulated and realized.

Description

technical field [0001] The invention relates to rock mass mechanics test technology, in particular to a high-temperature fissure rock mass penetration test device and a test method thereof. Specifically, the present invention is to test the permeability characteristics of fractures containing proppants with different particle sizes under different pressures and opening degrees under high temperature conditions. Background technique [0002] Permeability is an important property of porous and fractured media. The flow of water in the fractured rock mass is obviously different from the movement in the soil mass. In recent years, people have paid more and more attention to the particularity and importance of rock seepage itself. Engineering fields such as water conservancy and hydropower construction, rock slope stability, oil and gas development, underground engineering construction, mining engineering, and nuclear waste treatment inevitably encounter engineering geological ...
