Abstract: Through the research on the distribution and occurrence characteristics of coalbed methane resources in low rank coal
reservoirs in western China, it is believed that the gas content of coal reservoirs in northwest China is low, but because of the huge
thickness of coal seams, it contains huge coalbed methane resources, accounting for 53.1% of the total low rank coalbed methane
resources in China. However, the distribution of coalbed methane resources is extremely uneven, mainly distributed in Junggar
Basin and Tuha Basin in Xinjiang. The current development practice shows that the northwest region has a huge development
prospect, but the exploration and development are mainly concentrated in the local areas of the Zhungar Basin and Tuha Basin, so
it is still necessary to increase the exploration and development efforts and strengthen the evaluation of the strategic selection of
coalbed methane areas.
