Description
Technical Field
The invention belongs to the technical field of submarine natural gas hydrate development, and particularly relates to a submarine natural gas hydrate exploitation monitoring system.
Background
The natural gas hydrate is an ice-like solid compound with a cage-like structure formed by combining hydrocarbon gases with low molecular mass such as methane, ethane, propane and the like with water under the conditions of low temperature and high pressure, can be directly combusted, and is commonly called as 'combustible ice'.
Natural gas hydrates are widely distributed in sea areas with the water depth of 300-3000 m in the nature, a small part of the natural gas hydrates are located in permafrost zones, the methane hydrates are mainly 90%, and the reserves are huge. According to the estimation, the natural gas contained in the global natural gas hydrate is about 3 x 1016m3～3×1017m3Its heat equivalent is 2 times of the sum of all fossil fuels, including coal, oil and natural gas, which have been proven so far, and is available for human use for about 1000 years. Compared with the conventional oil gas resources, the natural gas hydrate has less pollution generated by combustion, is a real clean energy, and is expected to become one of the ideal alternative energy sources with the largest reserve after shale gas, dense gas, coal bed gas and oil sand in the 21 st century.
Although the research work of the natural gas hydrate is emphasized by many countries in the world, the problems of difficult mining technology, high development cost, large environmental hidden danger and the like become bottlenecks which restrict the mining of the seabed natural gas hydrate, particularly the environmental safety problem caused by the mining. The exploitation of the natural gas hydrate changes the temperature and pressure conditions under which the natural gas hydrate is subjected to, and causes the natural gas hydrate to be decomposed. If the control of the temperature and pressure conditions cannot be effectively realized in the exploitation process of the natural gas hydrate, a series of environmental safety problems can be caused, such as the intensification of the greenhouse effect, the change of marine ecology, seabed slump and the like.
Aiming at the possible environmental risks in the sea area natural gas hydrate exploitation process, the sea area natural gas hydrate exploitation process needs to be comprehensively monitored. However, although certain monitoring equipment is arranged in each of the 4 sea hydrate trial-production projects carried out in the sea area of the Nankai sea chest in Japan and the Nanhai God fox in China at present, the four environmental safety problems of the submarine natural gas hydrate development are not comprehensively monitored, and a set of complete submarine natural gas hydrate development environment monitoring system is not formed.
