Recently, the national development and Reform Commission approved the establishment of "to extend the oil Yanan national continental shale gas demonstration zone" (development and Reform Office of energy (2012) No. 2583), this marks the Shaanxi Yanchang Petroleum Group Yanan continental shale gas exploration and development has become the first national demonstration zone, also said that the exploration of Yanchang group in the Ming Dynasty the exploration of unconventional gas field has reached the international advanced level.

    The state approved demonstration area of 4000 square kilometers, "Twelfth Five Year Plan" period arrangement proved geological reserves of 150000000000 cubic meters or more, build capacity 500000000 cubic meters. Requirements to achieve three objectives: one is to establish the system of continental shale gas exploration and development technology. Construction of China's continental shale gas geological theory system, perfect the continental shale gas exploration and development technology, the preparation of continental shale gas exploration and development of industry standards. Two is to explore ways to improve the continental shale gas exploration and development of comprehensive benefits. The three is a summary of the formulation of fracturing fluid discharge and recycling specification, implementation of shale gas in green mining.

    In order to support the demonstration area to complete the mission objectives, the National Energy Board requested the relevant departments and local governments to actively coordinate the implementation of the policy shall enjoy, in the process of the construction of the outputs of the shale gas to use, not vent, the energy department to improve the shale gas trade, transportation, sale and use of supervision mechanism of the link, the implementation of market pricing, to encourage the investment subject pluralism of shale gas infrastructure.
