Analysis on suitability and tendency of China coalbed methane development technology

The coalbed methane development would include several stages and the final would be the match between the geology and the engineering. The geolog y would be the base to guide the engineering development. Meanwhile the feedback of the engineering development would be applied to continuously revise the geologi cal cognition. Based on the geological condition of the coalbed methane development in China, the paper summarized and analyzed the coalbed methane developmentt echnology and the geological suitability. Based on the discussion on the development tendency of the coalbed methane development technology at home and abroad, in combination with the coalbed methane development status in China, the paper stated the tendency of the coalbed methane development technology in China typical are as. The study showed that the coalbed methane survey and development in China would steadily be expanded to the West Guizhou and the East Yunnan, the south part of Junggar Basin, the West Henan and other places. The objects of the coalbed methane development would be developed from the shallow seam, medium and high ran k coal, single seam and coalbed methane mining only to the deep depth, low rank coal multi seams and coal measures gas and the relevant development technology als o would be steadily developed to the full mechanization and multi directions.
