Abstract

The invention discloses a system and method for quantitatively simulating the alkane oxidation process in a deep-sea depositional environment, and relates to the technical fields of marine natural gas hydrate resource development and environmental ecological engineering. Pressure simulation module, experiment module, and data acquisition control module; through the cooperation of each module, the temperature and pressure in the high-pressure simulation chamber of the environment are the same as the sampling points of the deep-sea environment during the whole experiment process, so as to realize the fidelity of the whole process of deep-sea sediment samples; through Quantitative alkane-containing fluid is injected into the deep-sea environment high-pressure simulation chamber for reaction to realize the quantitative study of the alkane oxidation reaction process in the deep-sea depositional environment; by injecting directional experimental fluid into the deep-sea environment high-pressure simulation chamber for reaction, the alkane oxidation reaction process in the deep-sea depositional environment is realized. Orientation changes.

Description

technical field [0001] The invention relates to the technical field of marine natural gas hydrate resource development and environmental ecological engineering, and more particularly, to a quantitative simulation system and method for alkane oxidation process in a deep-sea sedimentary environment. Background technique [0002] The deep-sea surface sediment layer is an important carrier connecting the deep-sea water body and the deep crustal environmental medium. Studies have shown that 80% of methane and other hydrocarbon-containing gases leaked from the deep environment undergo anaerobic oxidation reactions mediated by microorganisms in the deep-sea shallow sedimentary environment, which greatly reduces the proportion of hydrocarbon fluids entering the upper water environment and reduces the Serious negative impact on the marine water environment, and avoidance of entering the atmospheric environment, aggravating the global greenhouse effect and bringing about climate disas...
