油田水处理工艺及设备进展

Progress of Technology and Equipment in Oilfield Water Treatment

大多数油田都采用注水开发方式,随着油田进入高含水后期。采出水量也大幅增长,而油田采出水中不可避免地产生一些含油污水。出于环境保护和节约水资源的考虑,如何经济,有效地对含油污水处理是目前油田可持续发展的关键。通过对近年来国内含油污水处理的工艺流程、处理设备的研究,对油田水处理的发展方向进行了分析。

Nowadays most oilfields often applied with waterflooding. As domestic oilfields have enter highly water - bearing period, the amount of wastewater is increasing rapidly. Meanwhile the oil - bearing wastewater has emerged unavoidably in the effluent . in terms of environmental and resource saving, how to treat wastewater economically and effectively plays a key role on oil- field sustainable development, the development of the new foreign and home equipment and process flow on the treatment of oil - bearing sewage was introduced and the trend in the future was predicted in this paper.
