APPARATUS FOR MEASURING HYDRAULIC PROPERTIES OF ROCK SAMPLE

摘要

PURPOSE: A device for measuring hydraulic properties of a rock sample is provided to independently measure a specific storage coefficient and a water permeability coefficient of the rock sample. CONSTITUTION: A device for measuring hydraulic properties of a rock sample includes a rock sample holder unit (1100), a fluid supply unit (1200), a pump unit (1300), and a measurement unit (1400). The fluid supply unit injects a second fluid into a second injection hole (1130b) of the rock sample holder unit. The pump unit presses the second fluid supplied to a pumping hole (1130) via the second injection hole toward a first end portion of the rock sample received in an internal receiving space. The measurement unit includes a first pressure measuring device (1410) and a second pressure measuring device (1430). The first pressure measuring device is formed adjacent to the first end portion of the rock sample and measures the fluid pressure of a first closed space receiving the second fluid pressed by the pump unit. The second pressure measuring device is formed adjacent to a second end portion of the rock sample facing the first end portion and measures the fluid pressure of the second closed space receiving the second fluid penetrated through the rock sample.
