Three-dimensional mobile monitoring system for sea area hydrate exploitation environment

Abstract

The invention discloses a yhree-dimensional mobile monitoring system for a sea area hydrate exploitation environment, which comprises a mobile monitoring platform and a control unit thereof. The mobile monitoring platform comprises a main cabin body, and an environmental parameter monitoring unit, a topographic parameter monitoring unit, a cruise monitoring unit and a sampling unit which are arranged on the main cabin body and used for monitoring the surrounding environment and topographic changes of the drilling platform. An anchor system subsurface buoy working unit is further arranged behind the main cabin body, the anchor system subsurface buoy working unit is used for monitoring environmental parameters such as methane content and turbidity abnormity, and the anchor system subsurfacebuoy working unit stays at any height for monitoring under rotation of the winding vehicle. According to the system, various environment and other parameters are monitored in an omnibearing and three-dimensional mode in the circumferential direction and the vertical direction with each production well as the circle center, the situation that various cables are laid on the seabed or a workstation is established is avoided, the environmental effect of hydrate exploitation activities is comprehensively and effectively evaluated, potential environmental disasters are early warned in advance, and potential safety hazards are avoided. and a scientific evaluation system in the aspect of environment is provided for commercialized hydrate exploitation.

Description

technical field [0001] The invention relates to the technical field of exploration and exploitation of seabed natural gas hydrate resources, in particular to a three-dimensional mobile monitoring system for a sea area hydrate exploitation environment, which realizes monitoring, evaluation and prediction of the marine environment during the hydrate exploitation process. Background technique [0002] Natural gas hydrate is a solid ice-like substance formed by the combination of natural gas molecules and water molecules. It is currently considered as a new type of energy with great potential. The main component of which is combustible methane, so it is often called "methane hydrate". [0003] At present, countries such as Canada, the United States and Japan have successively carried out trial mining of methane hydrate on land and in the sea. For a large energy consumption country like my country, the scientific theory, resource evaluation, technical methods, Pilot mining, demon...

Problems solved by technology

However, in the context of the continuous increase in global energy demand and the gradual increase in carbon emissions, natural gas hydrate is not only a potential energy resource with huge reserves, but also an important source of greenhouse gases. At the same time, because 99% of hydrate resources Stored in the marine environment, in the process of exploration and development, it will inevitably cause risks such as submarine methane leakage, seabed displacement and subsidence, damage to biological communities, water pollution and even submarine landslides
