Abstract
Description
technical field
[0001] The invention relates to the field of basic physical property evaluation of natural gas hydrate reservoirs, in particular to a device and method for analyzing the mechanical properties of hydrate-containing sediments based on the combination of low-field nuclear magnetic resonance (LF-NMR) and triaxial experiments. Background technique
[0002] The dynamic response characteristics of reservoir mechanical parameters during hydrate production are crucial to the safety evaluation of hydrate test production. Artificially synthesizing hydrate-containing samples in the laboratory and performing core-scale mechanical test analysis are the main means to obtain the mechanical properties of hydrate-bearing reservoirs. However, large-scale tests can only obtain macroscopic mechanical parameters, and cannot describe the mesoscopic failure process of hydrate-containing sediments. Therefore, it is an important trend of current development to combine macroscopic mec...
