油田水处理新技术的应用进展

随着油田进入高含水后期,采出水量也大幅增长。同时,随着油田开发的深入,各种新的驱油技术如聚合物驱、三元复合驱进一步推广后,采出水的处理难度加大,处理成本上升。另外,对一些低渗透油田的利用开发,也提出了更高的水质要求。因此,含油污水的处理已成为国内各油田的技术攻关重点与难点。为此,国内各油田及其它相关机构单位在该方面做了大量的工作。对近年来国内含油污水处理新技术应用情况作了简要介绍,为今后油田水处理发展方向提供技术参考。

Progress in application of oilfield water treatment technology

As the oil into the high water cut stage,the amount of water also significantly increased at the same time.And with the oil field development in depth,a variety of new flooding technique further.Produced water treatment more difficult,and increased water treatment costs.In addition,some low-permeability oil field development,but also set a higher water quality requirements.Therefore,the oily wastewater treatment,has become the focus of various fields of technology research.To this end,domestic oil fields,an...
