Abstract: Exploration and development of non-conventional natural gas has become a main trend for the world. This article defines the conceptions of nonconventional natural gas reserves and elaborates on underground absorption and current conditions of China's non-conventional natural gas as well as the two-element practice experience and exiting issues. It briefs about the future development plan and comes up with the related implementation measures and workable suggestions. China is rich in non-conventional natural gas resources and has a promising prospect for development. It is necessary to step up basic research in this sector and borrow the experience and technological route in large-scale and effective development of compact (low permeability) oil and gas. Development pattern of low-permeability oil and gas in Ordos Basin and successful experience in US shale gas development should be brought under consideration so as to seek the methods suitable for China's geological and surface conditions and open up "a way for development of non-conventional resources with the Chinese characteristics" in the joint efforts.

Key words: non-conventional natural gas, low-permeability, compact gas, CBM, shale gas, resources, development

摘要： 非常规油气资源的勘探开发已为世界之大走势,文章阐述了非常规天然气资源的概念以及我国的地下赋存情况、开发现状、二元论的实践经验、存在的问题;介绍了今后的发展规划,提出了相应的实施措施和可行的建议。我国非常规天然气资源十分丰富,发展前景广阔,应加强基础研究,借鉴致密(低渗透)油气规模有效开发的基本经验与技术路线,参考鄂尔多斯盆地低渗透油气开发模式,汲取美国开发页岩气的成功经验,探索适合我国地质与地面条件的路径,协同创新、合作开发,开创"中国式的非常规资源开发之路"。
