摘　　要：随着油田的开发生产,平台对含油污水的处理量逐年增加,核桃壳过滤器的处理压力也不断增大。核桃壳过滤器作为污水处理系统的第三级设备,主要作用是对加气浮选器处理后的生产水进行过滤分离,去除水中污油和悬浮物,一旦出现问题,不合格的注入水将会导致地层孔隙堵塞,不仅对油井产量、注水开采效果产生极大的负面影响,同时也会导致环境的污染。文章通过对海上平台现场投用的核桃壳滤器的实验追踪,从核桃壳滤料流失这一问题为论点,分析了滤料流失的原因,在保证出口水质的前提下,通过调整核桃壳反冲洗流量和改变反洗程序控制逻辑,降低了核桃壳滤料的流失量,为油田“注够水、注好水、有效注水和精细注水”提供了有力保障。With the development and production of oil fields,the amount of oil-bearing sewage treated by the platform increases year by year,and the treatment pressure of walnut shell filter is also increasing.Walnut shell filter as the third level equipment of sewage treatment system,the main function is to filter and separate the production water treated by the aerated flotation device,remove the dirty oil and suspended matter in the water,once there is a problem,unqualified injected water will lead to the formation pore blockage,not only on the production of oil wells,water injection mining effect has a great negative impact,but also lead to environmental pollution.Based on the experimental tracking of the walnut shell filter used in the field of offshore platform,this paper analyzes the reasons for the loss of walnut shell filter material from the point of view of the problem of walnut shell filter material loss.On the premise of ensuring the water quality of the outlet,by adjusting the walnut shell backwashing flow and changing the backwashing program control logic,reduce the loss of walnut shell filter material,for the oil field“enough water injection,good water injection,effective water injection and fine water injection”provides a strong guarantee.
