油田污水回注处理现状与展望

Current status and prospect of reinjection treatment of oilfield wastewater

在简要总结国内目前油田的含油污水的来源、特性及含油污水回注标准的基础上,着重介绍了近年来在油田含油污水回注处理上已经投入运行的工艺流程及技术现状,提出稠油和含聚合物驱的含油污水回注处理工艺开发将是近期含油污水处理研究的热点。

Based on the briefly generalization of the sources, the characteristics and the reinjection standard of the oilfield wastewater in China at the present time, the process procedures and the current status of the technologies for reinjection treatment of oilfield wastewater which had been already put in service in resent years were emphatically introduced. It was proposed that, the exploitation of process for reinjection treatment of wastewater containing viscous oil reservoirs and polymer-flooding would be the hot point of the research on oil-containing wastewater treatment in the near future.
