Title:
TRIAXIAL EXPERIMENT DEVICE FOR HYDRATE
Document Type and Number:
WIPO Patent Application WO/2021/003688
Kind Code:
A1
Abstract:
A triaxial experiment device for a hydrate, comprising a frame (1), a pressure chamber (2), an upper pressure assembly (3), a lower pressure assembly (4), a confining pressure assembly (5), a natural gas content detecting mechanism (6), and a hydrate saturation measuring mechanism (7), wherein the pressure chamber (2) is mounted in the frame (1) and internally provided with a working chamber; the pressure chamber (3) is provided with a confining pressure inlet-outlet (24), a gas inlet (25), and a gas outlet (26); the upper pressure assembly (3) and the lower pressure assembly (4) are mounted in the working chamber; the upper pressure assembly (3) and/or the lower pressure assembly (4) are connected to an axial extensometer (31); the confining pressure assembly (5) is communicated with the confining pressure inlet-outlet (24), and an object to be tested (8) is provided with a radial extensometer (41); the natural gas content detecting mechanism (6) is respectively communicated with the gas inlet (25) and the gas outlet (26); the hydrate saturation measuring mechanism (7) is communicated with the working chamber. Displacement and deformation of said object (8) are detected by the axial extensometer (31) and the radial extensometer (41), and content change and saturation of the natural gas in said object (8) are respectively detected by the natural gas content detecting mechanism (6) and the hydrate saturation measuring mechanism (7), so that the detection is more comprehensively and accurately.
