【摘要】 目前,我国页岩气开发水管理面临的主要问题是水力压裂耗水量大,以及采出水成分复杂、污染物多。根据国外页岩气开发水管理经验,总结了页岩气开发对水资源的影响和采出水处置的主要方式,并结合国情提出了我国页岩气开发水源应多渠道选择的基本对策,以及采出水处置应以回用于水力压裂为首选方式的基本水管理思路。最后,提出了目前我国页岩气开发水管理的首要任务,即开展采出水回用水处理理论研究和工艺技术设备开发,并跟踪高盐水脱盐新技术和新工艺的发展动向。更多还原

【Abstract】 Huge amount of water consumed by hydraulic fracturing, and complex components and pollutions from produced water are the main challenges to water management in shale gas development. According to global experiences, the influences of hydraulic fracturing on water resources and the main methods for the treatment of produced water were summarized. The strategies of multi-choices of water resources for shale gas development and the basic water management solution of reusing produced water for hydraulic fracturing as the first choice were proposed based on the situation in China. Finally, the primary task of water management of shale gas development in China was raised, that is the theory of reusing produced water should be studied, and the development of process and equipment should be carried out while the trend of new techniques and processes on high saline water desalination being tracked.更多还原
