Multi-parameter visual test apparatus for marine gas hydrate generation and decomposition

Abstract

The invention relates to a multi-parameter visual test apparatus for marine gas hydrate generation and decomposition, which comprises a reaction container, a seawater case, a methane gas bottle, an air compressor, and a marine gas hydrate generation and decomposition apparatus. Several observation windows are provided on a casing of the reaction container, the lower part of the marine gas hydrate generation and decomposition apparatus is provided in the reaction container, the upper part of the marine gas hydrate generation and decomposition apparatus is extended from the top of the reaction container and exposed outside the reaction container, a liquid nitrogen outlet and a liquid nitrogen inlet are respectively provided at the top end and the bottom end close to sidewall of the reaction container, the top of the reaction container is respectively connected with a temperature sensor and a pressure transducer through wires. The invention has the advantages of simple and compact structure, high integrated level and automation degree, and convenient operation; the pressure environment of water depth with 600m-2000m and the seabed temperature environment with temperature below 5 DEG C required by the generation of gas hydrate can be simulated, simultaneously the balance condition of temperature and pressure required by generation and decomposition of the gas hydrate can be regulated; the observation windows are reserved on the apparatus, thereby the visualization degree is high.

Description

technical field [0001] The invention relates to a test device, in particular to a multi-parameter visualized marine gas hydrate formation and decomposition test device. Background technique [0002] The main component of marine gas hydrate is methane, which is an energy mineral formed by the combination of methane and water molecules in seabed sediments under low temperature and high pressure environment. It has the characteristics of high energy density, huge resources, and cleanliness. It is a new type of energy in the 21st century, which is of great significance in resource development, environmental protection and global climate change. Due to the limitation of marine gas hydrate occurrence mode and mining technology level, several common methods are currently used for the development of marine gas hydrate, such as depressurization method, thermal method, chemical reagent injection method, CO 2 Replacement method, fluorine gas + microwave method and other main technolog...

AI Technical Summary

Problems solved by technology

Existing experimental devices are generally based on exploring the formation process of marine gas hydrate and its controlling factors, and the device that integrates the decomposition process and influencing factors has not yet appeared

At the same time, because the occurrence of marine gas hydrate requires a high-pressure environment, the visibility of the existing test equipment is poor, and the real-time observation of the hydrate formation process needs to be optimized and improved.
