摘　　要：针对长庆油田压裂作业用水量大与废水产生量大产生的环保压力与水量消耗量大的问题,通过对废水特征的分析以及对油田生产现状的调研,以回收再利用为目标,提出废水处理后作为油田回注用水、配制压裂液用水和配制聚合物溶液用水的再利用方式,分别分析了三种方式的用水要求,简要介绍了相应的处理方法,对油田废水处理与再利用研究有一定的借鉴作用。Aiming to the problem of environmental protection pressure and extensive water consumption with the contradiction of large water consumption and wastewater discharge,through the analysis of the characteristics of wastewaterand the study of oil field production status investigation and research,some recycling ways to treated wastewater such as oilfield reinjection,fracturing liquid preparation and polymer solution are proposed.Then water quality requirement and processing method of each method is introduced,which has a certain reference value to the research on oilfield wastewater treatment and recycling.
