Abstract

The invention relates to a biogeochemical effect simulation experiment system under the methane leakage condition. A methane gas source is connected with a gas inlet arranged at the bottom part of a reaction kettle in a thermotank through a mute air compressor, a gas booster pump, a gas storage container, a valve control flowmeter and a check valve. The gas storage container is connected with a hand crank through a back pressure value and a buffer tank. A constant flux pump is connected with the gas inlet through a microbial container and a seawater container. A vacuum pump is connected with the upper gas outlet of the reaction kettle. Depiction of the flow process of methane gas leakage and depiction of the related microbial action in the sedimentary deposit can be solved, and the biogeochemical behavior caused by methane leakage in the submarine sedimentary deposit can be objectively reproduced so that the students are enabled to understand the water-rock-gas-microbial interaction and the related microbial action in the sedimentary deposit, and the favorable equipment and the research method can be provided for researching the hydrate decomposition and formation mechanism and the associated environmental effects thereof.

Description

technical field [0001] The invention relates to scientific research equipment and experimental teaching equipment for natural gas hydrate associated biogeochemical action in sea areas, in particular to a simulation experiment device and experimental method for methane leakage related to the decomposition of sea area natural gas hydrate and its associated biogeochemical action. Background technique [0002] Energy, environment and development are important objects to be coordinated in the progress of human society. Finding a new type of clean energy is one of the important ways to deal with the relationship between the above three. As a brand-new, high-efficiency and clean energy with great potential, natural gas hydrate has attracted great attention from various countries and is considered as an alternative energy in the 21st century. [0003] The stability of gas hydrate is often controlled by conditions such as temperature, pressure, geothermal gradient, gas composition, a...
