Abstract

The invention discloses a deep sea sedimentary environment alkane oxidation process quantitative simulation system and method, and relates to the technical field of marine natural gas hydrate resource development and environmental ecological engineering. The system comprises a deep sea environment high pressure simulation cavity, an environment temperature simulation module, an environment pressure simulation module, an experiment module and a data acquisition control module; through cooperation of all the modules, the temperature and pressure in the environment high-pressure simulation cavity are the same as those of a deep sea environment sampling point in the whole experiment process, and full-process fidelity of a deep sea sediment sample is achieved; quantitative alkane-containing fluid is injected into the deep-sea environment high-pressure simulation cavity for reaction, so that quantitative research on the deep-sea sedimentary environment alkane oxidation reaction process is realized; directional experimental fluid is injected into the deep-sea environment high-pressure simulation cavity for reaction, and directional change of the deep-sea sedimentary environment alkane oxidation reaction process is achieved.

Description

technical field [0001] The invention relates to the technical field of marine natural gas hydrate resource development and environmental ecological engineering, and more specifically, to a quantitative simulation system and method for alkane oxidation process in deep-sea depositional environment. Background technique [0002] The deep-sea surface sediment layer is an important carrier connecting the deep-sea water and the migration of 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, thereby greatly reducing the proportion of hydrocarbon fluids entering the upper water environment and reducing The serious negative impact on the marine water environment and the avoidance of entering the atmospheric environment will aggravate the global greenhouse effect and bring ab...
