摘　　要：某气田水处理厂位于鄂尔多斯盆地的毛乌素沙漠,主要负责处理气田打井产生的气田水,处理后达标水全部回注地层。随着勘探开发力度增大,气田水量不断增加,达标水回注压力增大,且毛乌素沙漠生态环境脆弱,水资源匮乏,为了降低回注风险、落实水资源节约化目标,针对合理回用某气田水处理厂达标水展开了探究,主要介绍了某气田水处理厂水处理流程和回用现状,分析了达标水存在的主要水质问题,即高含盐量、高COD(生化需氧量),介绍了几种气田水处理技术,探讨了某气田水回用的去向,与增大达标水回用率的意义。A gas field water treatment plant is located in the Mu Us Desert in the Ordos Basin.It is mainly responsible for the treatment of gas field water produced by drilling wells in the gas field.With produced water volume of the gas field and the pressure of the standard water reinjection increasing,the ecological environment of the Mu Us Desert is fragile and water resources are scarce.In order to re-duce the risk of reinjection and implement the goal of water conservation,this paper mainly introduces the gas field water treatment process,reuses status of the gas field water treatment plant and analyzes the main water quality problems of the water that meets the standard,namely high salt content and high COD(biochemical oxygen demand).It introduced gas field water treatment technologies.This paper discusses directions of water reuse in the A gas field and the significance of increasing the water reuse rate that meets the standard.
