The unconventional natural gas resources are estimated to be rich in China. And the total technical recoverable resources of shale gas,tight gas and coal bed methane (CBM) are predicted to be around 31 TCM,which is approximately 1.5 times of China's conventional natural gas total. To speed up the development and utilization of the unconventional natural gas resources is of great importance for the long-term healthy development of China's natural gas industry. Study shows that the engineering technology innovation and state policy support play a key role in realizing the utilization with large scale of unconventional natural gas resources in China,and the road map of developing the unconventional resources in China may take three steps:the tight gas and CBM have a number of good realistic conditions to utilize in a large volume and should take the priority to speed up development as quickly as possible; shale gas needs a period of preparation and will become a active contributor from the point of mid-term view to make the utilization of unconventional gas resource come into truth. Gas hydrate needs much longer period of preparation and has a bright future of utilization in a long run. It is predicted that the annual production of unconventional gas in China will be as big as conventional gas production in around 2020,and the total unconventional gas production (gas hydrate not included) in China may possibly reach 310×10 9m3 in the year around 2030,which make up 2/3 of the nation's total gas production and will provide the major resource base to maintain the stable and healthy development of China's natural gas industry. <<
