滤器是海上生产平台处理流程中的一个十分重要的设备，有着广泛的应用。滤器的良好状态也对其下游设备和流程的安全稳定运行起着决定性作用。因此，滤器清洗也是海上生产平台一项常规工作。当某一滤器需频繁清洗时，会给作业现场带来大量工作量，同时也增加了作业过程中的安全风险。针对渤海某平台滤器清洗需求，分析现场流程特点和要求，优选滤器形式，对该滤器进行自动反冲洗改造，并在实践过程中取得了良好的效果。

The filter is a very important equipment in the processing process of offshore production platform， which has a wide range of applications. The good condition of the filter also plays a decisive role in the safe and stable operation of its downstream equipment and process. Therefore， the filter cleaning is also a routine work of offshore production platform. At the same time， it also increases the safety risk in the process of operation. According to the cleaning requirements of a platform filter in Bohai Sea， the characteristics and requirements of the field process are analyzed， the filter form is selected， and the automatic backwashing transformation of the filter is carried out， and good results are obtained in practice.
