Abstract

The invention discloses a triaxial experiment device for a hydrate. The triaxial experiment device comprises a frame, a pressure chamber, an upper pressure assembly, a lower pressure assembly, a confining pressure assembly, a natural gas content detecting mechanism and a hydrate saturation measuring mechanism. The pressure chamber is installed in the frame and internally provided with a working chamber. The pressure chamber is provided with a confining pressure inlet-outlet, a gas inlet and a gas outlet. The upper pressure assembly and the lower pressure assembly are installed in the working chamber. The upper pressure assembly and/or the lower pressure assembly are connected with an axial extensometer. The confining pressure assembly is connected with the confining pressure inlet-outlet,and an object to be tested is provided with a radial extensometer. The natural gas content detecting mechanism respectively communicates with the gas inlet and the gas outlet. The hydrate saturation measuring mechanism communicates with the working mechanism. The triaxial experiment device measures displacement and deformation of the object to be tested by the axial extensometer and the radial extensometer, and detects content change and saturation of the natural gas in the object to be tested by the natural gas content detecting mechanism and the hydrate saturation measuring mechanism more comprehensively and accurately.

Description

technical field [0001] The invention relates to the technical field of testing natural gas hydrate deposits, in particular to a hydrate triaxial experimental equipment. Background technique [0002] Hydrate deposits are a metastable structure with complex mechanical behavior characteristics. The mining process often involves microstructural changes such as hydrate phase transition, particle migration, and cement structure destruction. Mechanism analysis to clarify the formation mechanism of geological disasters such as stratum subsidence and submarine landslides induced by natural gas hydrate decomposition. [0003] The uniaxial and triaxial compression of sediments and rocks, as well as gas and water seepage and high and low temperature coupling tests are important test methods for testing sediments and rocks, which can accurately measure the impact of various indicators of natural gas hydrate on unconventional energy. Very important for extraction. There are many kinds o...
