油田污水处理技术在注水工艺中的应用

Application of Oilfield Wastewater Treatment Technology in Water Injection Process

油田在开采的过程中需要向储油层进行注压,才能确保油田开采的效率。目前中国应用较为广泛的注压方式是利用净化后的水资源对其油层增加压力,确保整体油田的采收率。在油田开采过程中所形成的水均为污水,达不到注水标准,如直接将污水注入会对此项工作造成一定威胁,因此油田注水工作前需要先对污水进行处理,才可用于进行油田开采注水。选择科学合理的污水处理技术,在油田开采工作中占据了重要地位,文章对油田污水处理技术在注水工艺中的应用进行了分析,结合当前油田开采需求,最终实现油田持续高产,确保整体采收率。

The oilfield needs to inject pressure to the interior to ensure the efficiency of oilfield mining.At present,the widely used pressure injection method in China is to use purified water resources to increase the pressure on the oil layer,to ensure the overall recovery of the oil field.In fact,the water formed in the oil field in the mining process is all sewage,because its sewage does not meet the mining conditions,and it cannot meet the water injection standard,and it will pose a certain threat to oilfield mining.Therefore,it needs sewage treatment firstly before the water injection.It must choose scientific and reasonable sewage treatment technology,which plays an important role in the oilfield mining work.Therefore,the application of oilfield sewage treatment technology in the water injection process is analyzed.Combined with the current oilfield mining demand,the continuous high yield is finally realized to ensure the overall recovery rate.
