Abstract

China's shale gas industry is developing rapidly, but the associated challenges of water resources shortage and water pollution are becoming more and more prominent. Hydraulic fracturing, the core process of shale gas extraction, consumes a large amount of water and produces refractory wastewater, closely linking shale gas fields with water resources. In this context, this article is to (1) summarize the characteristics of water consumption and wastewater production in typical shale gas fields; (2) introduce the current status of water intake and internal reuse and treatment of shale gas wastewater (SGW); and (3) analyse the challenges of water management in shale gas field. In order to promote the sustainable development of the shale gas industry, it is necessary to establish an efficient water management system according to local conditions. Making use of municipal reclaimed water in fracturing, promoting external reuse of SGW, strengthening the monitoring and safety guarantee of water use, and formulating national or regional water management guidelines can improve the utilization efficiency of water resources in shale gas fields.
中国大型页岩气田的高效水资源管理
中国页岩气产业发展迅速,但水资源短缺和水污染问题日益突出。水力压裂是页岩气开采的核心工艺,耗水量大,产生难处理废水,将页岩气田与水资源紧密联系在一起。在此背景下,本文拟:(1)总结典型页岩气田的用水和产废水特征;(2)介绍了页岩气废水的取水现状及内部回用处理;(3)分析了页岩气田水资源管理面临的挑战。为了促进页岩气产业的可持续发展,有必要因地制宜地建立高效的水资源管理体系。利用市政再生水进行压裂,促进SGW的外部回用,加强用水的监测和安全保障,制定国家或地区水资源管理指南,可以提高页岩气田水资源的利用效率。
