The invention provides a rough single-fracture seepage test device suitable for a supergravity environment. The rough single-fracture seepage test device comprises a metal base used for providing a fixed position and limiting the overall size of a test device, a composite water tank used for providing water pressure for a test and collecting overflow water and test tail water, a rough single-fracture model used for a seepage test, a monitoring system used for monitoring a flow and pressure of a fluid in the test device, and a supporting and fixing system used for fixing and supporting each test device. The device is characterized in that a centrifugal machine is used for generating a centrifugal force, water pressure required by the seepage test is provided through a water level difference, and a problem of a single-fracture seepage characteristic test in the supergravity environment is solved.
Description
technical field [0001] The invention relates to the technical field of seepage tests, in particular to a rough single-crack seepage test device suitable for high-gravity environments. Background technique [0002] In recent years, the state has vigorously developed strategic oil reserves to ensure the stability of oil supply and promote economic development and social stability. The underground water-sealed stone cave oil depot is one of the main forms of the current strategic petroleum reserve. The underground water-sealed stone cave oil depot uses natural rock mass as the main structure, uses the natural burial conditions of groundwater, and supplements the artificial water sealing system to seal oil and its products in artificially excavated underground super large caverns. Its safety and sealing It is closely related to the seepage characteristics of fractures. [0003] The fractured rock mass contains a large number of joint fissures, which are the main channels for f...
