Abstract
A method for testing the nanomechanical properties of natural gas hydrate samples is provided. A dry pure nitrogen environment and a partial ultralow-temperature liquid nitrogen test condition are constructed, a micro-positive pressure state in a glovebox is maintained, and the temperature of a milling tool and a sample stand are maintained consistent; then, a hydrate sample is transferred and installed in the dry nitrogen environment, and the milling tool is driven to cut a surface of the natural gas hydrate sample to form a relatively flat surface; next, indentation parameter reliability testing is performed, an indentation load is changed, indentation testing of indentation points is performed, and an indentation form is observed. The method can realize indentation testing of natural gas hydrate samples in an ultralow-temperature and dry environment by means of a nanoindenter.
