摘　　要：页岩气作为一种重要的非常规资源,对于中国能源安全和供给至关重要,但由于页岩储层表现出低孔、特低渗的特征,必须通过水力压裂才能获得理想经济产量。根据页岩气开采的特点,综述了北美地区先进的开采技术,结合中国页岩储层特征和开发现状,探讨了中国页岩气大规模开发的研究方向。分析表明:北美地区页岩气井的经济开发得益于储层评估、水平井钻井和压裂技术的进步。指出中国在借鉴、参考北美地区页岩气先进开采经验的同时,应结合中国储集层特性通过开展勘探开发全过程优化、体积压裂机理及配套、页岩气开发负面效应评价等方面的攻关,实现中国页岩气的高效、经济开发。Shale gas as an important unconventional resource, is essential for our energy security and supply, but the shale reservoir is of low porosity and extra-low permeability characteristics, and hydraulic fracturing is needed to obtain the desired economic output. We summarized the advanced technology used in American shale gas exploitation in the paper. Based on the shale gas reservoir characteristics and technology development of China, we also discussed the directions of large-scale development of shale gas in China. The results indicate that economical development of north American shale gas benefited from the advanced reservoir evaluation, horizontal drilling and hydraulic fracturing. And we also further evaluated the latest developments in north American shale gas, including reservoir evaluation, fracturing material and design optimization, production evaluation. In addition, discussion of technology adaptability and basic principles of various technologies are presented. In order to improve the development of shale gas in China, from exploration to development, we should learn from combining advanced experience with our reservoir features to carry out science and technology research, such as whole optimization of exploration and development, the volume fracturing mechanism and related technology, the evaluation of negative effects of shale gas development.
