纤维球过滤器是压力过滤器中较为新型的水质精密处理设备。以前在含油污水回注处理方面一直采用的是双滤料过滤器、核桃壳过滤器、砂滤器等。特别是
在低渗透油层,注水用精细过滤技术一直达不到低渗透油层注水要求。
Fiber ball filter is a relatively new type of precision water quality treatment equipment in pressure filter. In the past, double filter
media filter, walnut shell filter, sand filter and so on have been used in the reinjection treatment of oily sewage. Especially in low
permeability reservoirs, fine filtration technology for water injection can not meet the requirements of water injection in low permeability reservoirs.
