Analysis on Coalbed Methane Development Mode and Utilization Technology in China

Coal bed methane (CBM), as a new energy, has become an important supplement to natural gas in China. Development and utilization of CBM can also reduce greenhouse gas emissions and protect of ecological environment. Very different forms of the Chinese CBM extraction, but the basic mode can be classified as Jincheng mode, Huainan mode and virtual reservoir mode. Ventilation air methane (VAM) use and safe transportation for low concentration CBM technologies have become the bottleneck restricting CBM utilization. CBM development mode and bad utilization problems are summarized and presented in time, which will contribute to the development of Chinese CBM industry and energy-saving and emission reduction.
