The invention discloses a natural gas hydrate simulation experiment apparatus. The simulation experiment apparatus comprises longitudinal reaction equipment and transverse reaction equipment, wherein a sapphire reaction kettle is arranged in the longitudinal reaction equipment in a communication manner; visualization equipment is correspondingly arranged on one side of the sapphire reaction kettle; a temperature gradient control layer and a probe measuring system are arranged on the longitudinal reaction equipment, the transverse reaction equipment and the sapphire reaction kettle; the probe measuring system is connected with a data acquisition processing system; air intake, pressurizing and drainage pipelines are arranged at the bottom of the longitudinal reaction equipment. The simulation experiment apparatus can realize that the temperature in a container is in gradient distribution and hydrate is synthesized in the local layer section in the container; gas enters from the bottom of the container and moves upwards in a dispersive manner, and the synthesis and decomposition of the hydrate are effectively simulated; the temperature, pressure distribution and the saturation change of the hydrate can be measured in real-time; the influence study of exploiting simulation in a mass transfer process can be conducted; the formation rule and the hydrate mass transfer and decomposition rule are further known.
Description
technical field [0001] The invention relates to an experimental device, in particular to a natural gas hydrate simulation experimental device based on a mass transfer process. 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.
