摘　　要：目前我国绝大多数油田已进入开发中后期,三次采油技术得到广泛应用,大量的聚合物及表面活性剂等与油田回注水一同进入深层地下,并随着原油开采进入油田采出水中,造成油田采出水的水质特性变得更为复杂,处理难度增大,同时增加了潜在的生态环境风险。随着我国生态环境保护力度的加大,油田采出水外排标准及作为回注水使用的标准也将日益严格,仅依靠现有的油田采出水成分分析数据及处理技术将无法满足生态环境保护要求。基于此,对油田采出水成分及处理技术进行初步分析,为下一步油田采出水的深度处理及环境监测提供研究思路。At present,most of the oil fields have entered the middle-late period of development in China,and the technology of tertiary oil recovery has been used widely.A large number of polymers and surfactants enter deep underground together with the oilfield injection water,and enter the oilfield produced water with the crude oil exploitation.As a result,the characteristics of the oilfield produced water quality become more complex,which increased the difficulty of processing,and the risk of ecological environmental is increased.As ecological and environmental protection becomes increasingly strict in China,the effluent standards and injection of oilfield produced water will be increasingly strict.Only relying on the existing analysis data of oil field produced water composition and processing technology will not meet the requirements of ecological environment protection.Based on the above considerations,preliminary analysis of the composition and treatment technology of oilfield produced water are made in this paper,which provides research ideas for the advanced treatment and environmental monitoring of oilfield produced water.
