摘　　要：目前 ,国内外处理采油污水的方法主要有隔油处理法、气浮法、凝聚过滤法、化学处理法、生物处理技术、吸附法、膜分离技术、井下油水分离技术和三相旋流分离器技术。国内各油田对采油污水普遍采用的隔油除油 -混凝 -过滤三段处理工艺存在较多问题 ,给油田生产和环境保护造成一定困难。为此 ,设想了采用井下油水分离器、三相旋流分离器和膜分离 3项新技术的采油污水处理工艺流程 。Various techniques for oilfield wastewater treatment at home and abroad are expounded. And it is pointed out that the widely-used oil removal-coagulating-filtering method has some disadvantages and especially will do harm to the environment. Thereby a new technique using jointly downhole oil-water separator, three-phase hydrocyclone and membrane separation is proposed. The prospect of oily wastewater treatment is forecast.
