气田水综合治理成套技术研究

Research on Packaged Technology of the Comprehensive Treatment on Gas Field Water

随着天然气开发力度的加大,伴生的气田水也大量产生,对环境造成巨大影响,急需开发一种经济有效的气田水综合治理技术以满足需求。本文针对川东某地气田水的特点,通过系列实验研究,开发出了从预处理到脱盐结晶、再到生化处理的气田水综合治理成套技术,对COD和盐分的去除效果好,最终出水达到排放标准,解决了气田水治理难题,为下一步应用打下了基础。

With the increasing exploitation of the natural gas, the concomitant gas field water is generated substantially. It will have a great impact on the environment, and it is urgent to develop an economic and efficient technology to treat the gas field water comprehensively. This paper, according to the traits of the gas field water in the East of Sichuan and a series of experiments, develops a packaged technology of comprehensive treatment on the gas field water （from pretreatment to desalted crystal, and then to biochemical treatment）. This technology has a great impact on eliminating COD and salinity, and enables the effluent achieves the emission standard. It will not only tackle the problem of treating the gas field water but also lay the foundation of further application.
