ABSTRACT

Natural gas hydrate mainly exists in the unconsolidated sediments in the sea area as a solid state. It is a kind of green and clean energy with large reserves and high unit calorific value. It is another potential strategic alternative energy after tight sandstone gas, shale gas and coalbed methane. Based on the extensive investigation of the research results of natural gas hydrate at home and abroad, this paper expounds the current situation of global hydrate investigation and production test, defines the potential distribution of global hydrate, discusses the key problems to be solved in the commercial development of hydrate, and analyzes the secondary disasters caused by hydrate development. Finally, some policy suggestions and technical direction of exploration and development are given.
