The principal structure and the operating principle were presented for oil/water separation of dynamic hydrocyclones, whose designing methods of structural performance and manufacturing engineering were described, which were made through a indoor test and a field trial. It is verified that the prototype can treat the concentration of oily water from 1.00～ 1.80 g/L to 0.02 g/L or so, so separating efficiency of oil/water is up to 95 percent. Compared with static hydrocyclones, dynamic hydrocyclones can treat more exiguous oil droplet, with a pressure loss as low as 0.01～0.15 MPa. The process of field test has been analyzed. We have put forward a better process of measures to treat with the produced fluid of polymer driving, and have given a concrete plan to improve the precision equipment.
