摘　　要：随着常规能源的不断消耗,能源需求持续上涨与能源缺乏的矛盾日益突出,页岩气的开发为全球能源供需压力的缓解指明了方向。然而,页岩气的持续开采对环境的影响也逐渐显露出来,尤其是水力压裂法在开采过程中可能出现的一些不容忽视的水环境问题,如对水资源需求消耗过大,地表水与地下水污染等。这些问题在一定程度上威胁着生态环境及人类日常用水的安全,在环保问题日益严峻的今天,应当更为重视。基于水环境问题,参考国外页岩气开采的经验,结合我国页岩气开采的现状进行研究,深入分析了页岩气开采的环境影响因素,探讨了如压裂液重复利用、无水压裂等页岩气开采用水的处理技术,为页岩气开采用水处理方法提供了理论基础,并且对未来页岩气开发具有一定指导作用和参考价值。With the continuous consumption of conventional energy,rising energy demand and the lack of energy has become increasingly prominent contradiction,the development of shale gas can help to solve the problems of the global energy supply and demand pressure. However,the impact of the shale gas industry on the environment is becoming more and more obvious with the continuous exploitation of shale gas,especially some water environmental problems cannot be ignored may occur in the mining process of Hydraulic fracturing,such as excessive consumption of water resources demand,pollution of surface water and groundwater,etc. It should be more attention due to the environmental issues in the increasingly serious today. With the reference to the experience of successful exploitation of shale gas abroad,combined with the research of present situation for shale gas exploitation in China,in this paper,the environmental impact factors of shale gas exploitation were analyzed in depth,and the treatment technologies of shale gas exploitation,such as fracturing fluid reuse,and water fracturing were discussed,which provides a theoretical basis for water treatment of shale gas exploitation,and has a guiding role and reference value for shale gas exploitation in the future.
