油田采出水新型处理工艺技术应用及评价

Application and evaluation of new technology for produced water disposal in oilfield

随着油田开发进入中后期,采出水量逐年增加,采出水出路成为制约油田"可持续"发展的一项重大难题。而实现采出水合格处理后有效回注,不仅是解决油田采出水出路的根本途径,也是国家"节能减排、环保治理"工作的重点。

With the development of the field go into intermediary and later stage ,the produced water is higher, The reinjection of produced water after treatment in oilfield has become a great problem which affect sustainable development. So sewage circular injection after disposal is not only the way to resolve produced water disposal,but also the key to Energy-saving emission reduction and Environmental governance,moreover, since the produced water after treatment in our oilfield must reinject low permeability layer ,this make reinjected water has higher requirements. In recent years,technical staff in our Institute actively research and introduce three kinds of advanced technology for produced water in oilfield, which can make the water quality after treatment to be improved.
