Abstract

Abstract:

China is just starting the industrial development of shale gas due to its great potential in shale gas resources although domestic researches on the comprehensive assessment, production mechanisms and production technologies of shale gas remain immature. Based on the authors' previous investigation and extensive literature search, this paper gives an overview on advances in the research and development of shale gas both at home and abroad, which discusses the following aspects: (1) the comprehensive assessment of shale-gas resources is the first step in shale-gas exploration and development and the key parameters and factors that determine the potential of shale gas are analysed; (2) production mechanisms of shale gas are fundamental to reservoir modeling, numerical simulation and hydro-fracturing design, and therefore, the complex production mechanisms and flow models are summarized. (3) some key technologies applied to shale-gas development, such as horizontal well and hydraulic fracturing, and the intrinsic correlation between reservoir characteristics and technologies chosen are discussed, which provide a reference basis for production optimization; (4) a review of the development history, characteristics and future development expectation of shale-gas resources in China.

Key words: shale gas, comprehensive assessment, production mechanism, horizontal well, hydraulic fracturing, fracture monitoring

摘要：

中国页岩气资源具有广阔的开发前景。目前中国尚未实现页岩气的工业开发,对页岩气综合评价、采出机理、开采技术的研究还不成熟。基于前期研究及文献调研,对国内外页岩气的研究进展以及美国页岩气开发经验进行了归纳总结,探讨以下几个方面:1综合评估页岩气资源是开发的第一步,分析了决定页岩气开发潜力的各个参数;2深入研究页岩气的采出机理对开展数值模拟和指导压裂设计有重要意义,总结了页岩气的复杂开采机理及流动模型;3页岩气开发中的关键技术主要是水平井与水力压裂,重点揭示了储层特点与技术之间的内在联系,为优化开采提供参考;4回顾中国页岩气的开发进程和资源特点,展望未来开发前景。
