摘要
页岩气是一种清洁、低碳、高储量的非常规天然气能源,已成为全国油气资源勘探开发的新亮点,其快速发展影响着世界能源格局。然而,页岩气开采带来了巨大的环境风险,如水污染、大气污染、固体废弃物污染和土壤污染等。文章主要分析了页岩气钻井过程、压裂过程及采气过程可能出现的水环境问题,如水资源消耗、地表水污染及地下水污染等;总结了针对不同类型废水的处置措施及处理技术,以期为处理页岩气开采过程中产生的不同类型的废水提供理论依据。
Shale gas is a clean, unconventional energy with low carbon and high reserves. It has become the new bright spot, and affects the pattern of world energy. However, shale gas exploration has brought great environmental risk, such as water, air, solid waste and Soil pollution. In this paper, the water pollution such as water consumption, ground water pollution and surface water pollution are analyzed in the drilling, fracture and extracting gas process. The disposal measures and treating technology are summarized for various types of wastewater in the hope of providing theoretical basis for various types of wastewater treatment.
