Aiming at the geographical characteristics of China's coalbed methane (CBM) fields and the problems of CBM surface low-pressure gathering, this work proposes a new CBM surface gathering approch suitable for the current situation of China, which combines both the centralized mode and the distributed mode. We made a joint research and achieved a great technological breakthrough on key technical and scientific issues within the CBM low-pressure gathering system, especially particularly focusing on low-pressure gas gathering technology, skid-mounted liquefaction equipment development, producedwater treatment, environmental protection technologies, and automated data collection and network based on management for CBM production and gathering system. It has formed a complete CBM surface gathering and monitoring process technology adapting to the features of China's CBM industry, and developed a series of low-cost, safe, economic and practical production equipment and commissioning systems, and all innovation results have been applied in the China’s national CBM development testbed project.
