Abstract:

Domestic natural gas production is the basis of China's natural gas industry layout. It is of great significance to predict the medium and long-term production trend of China's natural gas industry. Compared with the United States, natural gas E&P in China shows the same trend of parallel development of both conventional and unconventional gas, while the shift from conventional gas to unconventional gas shows a more aggressive pattern in China. This article presents a detailed review of the challenges to China's natural gas in the aspects of resource characteristics, development technology, economic effectiveness, organization and management, safety and environment. Then the progress and development direction of exploration and development theory and technology is discussed. The potential of conventional and unconventional natural gas exploration and development is evaluated in this paper. The total domestic natural gas output is predicted to be 2 600 × 108 m3 in 2035, with the conventional natural gas production stabilizing at 1 360 × 108 m3, the unconventional natural gas production increasing to 1 150 × 108 m3 and the dissolved gas output of 90 × 108 m3, which is the decision basis of energy structure adjustment and strategic layout of import pipeline and gas storage in China.

Key words: Natural gas, Development trend, Active replacement, Technical progress, Industrial layout, Decision basis
