页岩气开发面临的环保挑战及建议

我国的页岩气勘探开发处于起步阶段，还未建立完善的环保政策，大规模开发将面临诸多环保挑战。我国页岩气主要分布在四川、重庆等南方地区，结合该区域地少人多、地质灾害多发等特点，文章从页岩气压裂作业所需水资源、大量压裂返排液和地层水无害化处理、勘探开发过程中噪声污染以及开发用地与耕地之间的矛盾等方面探讨了页岩气开发面临的主要环境风险，并提出了页岩气开发的环保对策建议。

Environmental Challenges and Suggestions in Shale Gas Development

Exploration and development of shale gas in China is still in infancy. Environmental protection policy has not been established and large-scale exploration will face many environmental challenges. Shale gas is mainly distributed in Sichuan, Chongqing and other southern areas of China. Combining with the characteristics of dense population, geological disasters in those regions, this article discusses the major environmental risks in shale gas exploration from water resource requirement of shale gas fracturing operation, harmless treatments of massive fracturing fluid and formation water, noise pollution and the contradictions between constructed land and cultivated land, and puts forward the environmental protection countermeasures of shale gas development.
