摘要
页岩气作为重要的非常规天然气资源,已成为全球能源领域的新亮点,但其开采技术独特,由此可能引发新的水污染和水资源短缺问题。详细介绍了页岩气开采废水(压裂返排液)的水质特征、污染成因以及处置方式,并对国内外压裂返排液处理工艺的原理、适用条件和存在问题进行总结和分析,在此基础上指出我国页岩气返排液处理未来可能的发展方向,为今后国内页岩气开发提供技术参考。
Shale gas, as an important unconventional natural gas, has become one of the hot topics in the global energy field. However, it may bring new water pollution and water resource shortage problems because of its special exploitation technology. In this paper, the water quality characteristics, pollution causes and disposal methods of the fracturing flow - back fluid of shale gas exploitation were introduced. Meanwhile, the mechanisms, application conditions and existing problems of the fracturing flow - back fluid treatment technologies are all summarized and analyzed in detail. Then, the probable develop direction of shale gas fracturing flow - back fluid treatment is put forward, which could provide reference for the domestic shale gas exploitation.
