Description

technical field [0001] The invention relates to a mobile natural gas hydrate evaluation device, which belongs to the field of petroleum and natural gas. Background technique [0002] Since the 1990s, with the gradual deepening of people's understanding of gas hydrate, gas hydrate, as an important strategic resource and a potential geological environment influencing factor, has been deeply and comprehensively studied all over the world. Undoubtedly, laboratory-scale simulation experiment research is an important part of it. At present, hydrate research methods show interdisciplinary and interdisciplinary application characteristics, and a large number of novel technologies and methods have been applied to hydrate research. , there are three main approaches: direct application in in-situ testing devices; using modern testing techniques to study hydrate samples; transforming testing instruments to make them suitable for in-situ testing of hydrates. [0003] Natural gas hydrate...
