Abstract

The invention discloses a monitoring system for land area natural gas hydrate exploitation. The monitoring system comprises an atmosphere monitoring unit, an earth surface monitoring unit and a reservoir monitoring unit, namely an atmosphere-earth surface-reservoir 'three-in-one' environment monitoring system. The monitoring system is clear in structure, comprehensive in function and capable of realizing omnibearing monitoring of land area natural gas hydrate exploitation, a guarantee is provided for reducing the environmental risk of land area natural gas hydrate exploitation so as to achievesafe and efficient exploitation, and wide application prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of land natural gas hydrate development, in particular to a monitoring system for land natural gas hydrate exploitation. Background technique [0002] Natural gas hydrate is an ice-like solid compound with a cage structure formed by combining low-molecular-weight hydrocarbon gases such as methane, ethane, and propane with water under low-temperature and high-pressure conditions. It can be directly burned, commonly known as "combustible ice". [0003] Natural gas hydrates are mainly distributed in sea areas, but a small part is located in land permafrost. In my country, natural gas hydrates have been found in the tundra of the Qinghai-Tibet Plateau and the tundra of the Northeast. According to rough estimates, their resources are about 12.5×10 12 m 3 and 2.8×10 12 m 3 . It is estimated that the natural gas contained in natural gas hydrates in the world is about 3×10 16 m 3 ~3×10 17 m 3 , its thermal ...
