油田回注水的处理方法及工艺

Oilfield Reinjection Water Treatment Method and Process

油田注水是油田开发过程中向地层补充能量,提高油田采收率的重要手段之一。原油采出后造成地下亏空,为了保持或提高油层压,获得较高的采收率,使得油田注水在油田开采中得到越来越广泛的应用。油田回注水处理工艺是极其复杂的,而每一种的处理方式都不尽相同,所以把握好油田回注水处理的方法就尤为必要。本文介绍了油田回注水常见的细菌类型及其处理的工艺方式,并对该回注水样进行灭菌实验,取得了良好的试验效果。油田回注水的处理工艺必须要跟上时代发展的步伐,寻求更高层次的发展模式,那将是油田发展的又一个春天。

Water injection in oil field is one of the important means to increase energy recovery in oilfield development. In order to maintain or increase reservoir pressure and obtain high recovery rate, oil field flooding has been applied more and more widely in oilfield production. Oilfield reinjeetion water treatment process is extremely complex, and each treatment method is different, so it is necessary to grasp the method of oilfield reinjection water treatment. In this paper, the common bacteria types and treatment methods of reinjection water in oilfield are introduced, and the sterilization experiment of this reinjection water sample has been carried out, and good results have been achieved. Oilfield reinjection water treatment process must keep pace with the development of the times, and seek a higher level of development model, that will be another spring of oil field development.
