Abstract Aiming at major seepage problems in deep geotechnical engineering，a seepage and erosion device with a maximum core length of 1 500 mm was independently developed to reveal the seepage mechanisms of various fluids in deep strata，and seepage tests of saturated brine and gas in cores(off-white sandstone) were carried out. A general mathematical model describing the relationship among seepage velocity，seepage range and pressure gradient was established. The results demonstrate that，under the same temperature(50 ℃) and stress(16 MPa) condition，the seepage velocity of gas is extremely fast and about one hundred times of that of brine. The seepage of brine and gas is in accordance with Darcy?s law，and the test results are in good agreement with the theoretical calculations with a correlation coefficient of 99.8%. The relationship between the seepage range of brine and gas with time can be described by a power function，showing rapid growth in the early stage and gradual stabilization in the later stage. However，the seepage range of gas displace brine has no direct relation with time，which can be approximated as the combination of brine and gas seepage. In addition，the permeability and porosity of crystallized samples after brine seepage are lower than those of uncrystallized samples，which means that salt crystals have a certain filling and plugging effect on rock voids. This study confirms the feasibility and practicability of the developed device and provides a research method and idea for medium seepage in deep strata，which is helpful to reveal new scientific problems and to solve practical engineering problems.
