我国非常规天然气资源比较丰富，开发利用程度低，且有后发优势，加快非常规天然气资源开发利用对我国经济社会发展与能源安全具有重要战略意义。本文在客观评价四类非常规天然气资源潜力与开发趋势的基础上，提出了我国非常规天然气开发利用战略和措施建议。研究认为，我国页岩气、致密砂岩气和煤层气可采资源总量约为3.1×1013 m3，大约是常规天然气可采资源量的1.5倍，技术进步和国家政策扶持是实现非常规天然气资源大规模开发利用的关键。我国非常规天然气开发利用可采取“三步走”的路线，积极组织，加快发展，预计到2020年前后

The unconventional natural gas resources is abundant in China but with low degree of development and utilization. Moreover, there is advanced technology and experiences from outside China can be learned. It is of great strategic significance to accelerate the development and utilization of unconventional natural gas resources for economic and social development as well as the energy security. Based on the evaluation of the potential and exploitation trends of four types of unconventional natural gas resources, some strategies and measures were recommended in this paper. The studies suggested that the grand total technically recoverable resources of shale gas, tight gas and coal-bed methane in China is approximately 3.1×1013 m3, which is 1.5 times that of conventional natural gas resources. Both technological innovation and policy support from the government are the key to achieve the large-scale development and utilization of unconventional natural gas resources. A three-step strategy can be applied in the development and utilization of unconventional natural gas in China. The output of unconventional natural gas is predicted to draw equal with that of the conventional natural gas around 2020; it is expected to reach approximately 3×1011 m3 around 2030, accounting for 2/3 of the national total. It will be the main contributor for the sustainable and sound development of China’s natural gas industry.
