Key Technologies and Practices for Efficient Development of Coalbed Methane in China
Abstract：The development of coalbed methane has the 'threefold benefits' of ensuring mine safety, protecting the ecological environment, and providing low-carbon energy. After more than 40 years of theoretical research and practical production, significant progress has been made, but long-standing problems such as low single-well production and poor development efficiency have persisted. Through 'exploration evaluation + pilot testing', the eastern edge of the Ordos Basin has achieved a daily production of over 100 million cubic meters from horizontal wells in coal seams deeper than 1,500 meters, breaking through the 'forbidden zone' and world challenge of 'cost-effective development' of deep coalbed methane. This has potentially doubled the national coalbed methane resources from 36.81 trillion cubic meters to over 70 trillion cubic meters, demonstrating broad development prospects. At the same time, with the continuous deepening of exploration and development, a series of theories and technologies for deep coalbed methane exploration and development have been proposed, driving the coalbed methane industry into a new stage of development, and playing an important role in enhancing the value of the coalbed methane industry in ensuring national energy security and supporting the achievement of the 'dual carbon' goals.
