Abstract
The invention discloses a test sample sealing device for a high-temperature and high-pressure measurement for the shear-flow of rock, belongs to the field of rock mechanics, and solves the technical problem that a rock test sample is liable to break when temperature is up to 600 DEG C. A pressure kettle in the test sample sealing device disclosed by the invention is of a variable-inner-diameter thick-wall structure, a high-temperature-resistant sealing sleeve is of a sealing copper sleeve structure, and the sealing copper sleeve is laterally wrapped by two thick-wall semi-cylinders to form a combined body, and the combined body is arranged in the variable-inner-diameter thick-wall pressure kettle; the connection flange of the thick-wall pressure kettle is connected with an external axial pressure loading device through a bolt, and the fastening force of a bolt extrudes a sealing copper gasket on the end surface of the pressure kettle and the end surface of the sealing copper sleeve, thus realizing sealing for the test sample and the cavity of the pressure kettle on the end surface of the copper sleeve. Therefore, the test sample sealing device disclosed by the invention is reasonable in structure, and not liable to damage the sealing copper sleeve when the temperature is up to 600 DEG C, thus improving the sealing reliability, and facilitating to realize measurement on a shear-flow at high temperature of 600 DEG C, under a high pressure and with a large shear displacement.
Description
technical field [0001] The invention belongs to the field of rock mechanics, and in particular relates to a sealing device for measuring rock shear seepage at high temperature and high pressure, and is especially suitable for a sample sealing device for measuring rock shear seepage at 600°C high temperature and high pressure Background technique [0002] The shear seepage of rock is the basis for the study of major geological disasters, such as the mechanism of earthquakes and landslides, the activation mechanism of faults induced by hydraulic fracturing in the development of energy resources, etc. At present, the measuring devices for rock shear seepage include: the measuring device for direct shear seepage under normal temperature and low pressure (confining pressure less than 20MPa); the measuring device for oblique shear seepage under normal temperature and high pressure; the measuring device for oblique shear seepage under high temperature and high pressure. There is a ...
