Device and method for simulating and dynamically monitoring shallow sea environment

Abstract

The invention discloses a device for simulating and dynamically monitoring a shallow sea environment and a method for using the device. The device comprises: a plurality of reaction pipelines, circulating cold water jackets arranged in the reaction pipelines and reaction columns arranged in series, a liquid injection assembly which is used for injecting liquid into the reaction column and comprises a solution storage tank and a pump communicated to the solution storage tank; a gas injection assembly which is used for injecting gas into the reaction column and comprises a gas source and a pressure regulating valve communicated to the gas source; and a monitoring assembly which comprises one or more sensors, wherein a plurality of probe holes are formed in the side wall of each reaction pipeline, the probe holes are communicated with the reaction columns, and probe sealing columns or plugs of sensors are installed in the probe holes so as to sense environmental parameters in the simulation period.

Description

technical field [0001] The present disclosure relates to a simulation device, in particular to the field of seabed environment simulation and monitoring. Background technique [0002] Marine gas hydrate (hereinafter referred to as hydrate), also known as "combustible ice", is a clean, efficient, and huge reserves of new energy, and is also considered the best substitute for traditional oil and gas resources. The effective component of hydrate under the seabed is methane. Any sea area suitable for hydrate mining must have a large supply of rising methane. Hydrate pools mainly occur in unconsolidated sedimentary layers on the seabed. Upwelling fluid migration processes, methane geochemical reaction processes, and hydrate reservoir emplacement will all modify the properties, geochemistry, and eco-environmental conditions of sediment layers, seawater-sediment interfaces, and water bodies. If large-scale commercial mining is very likely to destroy the fragile ecological environm...

AI Technical Summary

Problems solved by technology

If large-scale commercial mining is very likely to damage the fragile ecological environment of the mining area, improper disposal may even lead to large-scale ecological and environmental disasters

[0003] Due to the complexity of hydrate mining and the seabed environment, conventional on-site monitoring of oil and gas mining is not suitable for the mining of natural gas hydrates. Therefore, it is necessary to propose monitoring methods for environmental problems such as methane leakage that may be caused by seabed gas hydrate mining.
