摘要
采用水力压裂法开采非常规气时,成分复杂、高盐度的采出水需经简单处理后回注地层。此过程可能引发的环境风险逐渐受到各界关注。针对采出水回注的井位层位、回注水水质等环境风险,综述了室内高温高压静态反应釜实验、动态驱替实验、数值模拟、分析评价等方面的研究进展,在此基础上提出了该领域研究存在的问题和发展方向,为我国采出水回注环境影响研究提供借鉴。
When unconventional gas is developed through hydraulic fracturing,the produced water with complex composition and high salinity should be simply treated and then reinjected into formation.The environmental risk of the process has gradually drawn attention from all walks of life.Aiming at the environmental risks of well location for produced water reinjection and water quality of reinjection water,the research progresses of indoor high temperature and high pressure batch experiment,dynamic core-flooding experiment,numerical simulation,analysis and evaluation are summarized.On this basis,this paper puts forward the problems and development direction of this research field,so as to provide reference for the research on environmental impact of produced water injection in China.
