Abstract: Research on the technology of polymer injection allocation have been carried out in this paper by effective utilization of oily sewage, for the situation of the tensions of polymer flooding water usage, the protrusive disadvantages of polymer dilution and preparation in Daqing oilfield. Technical support to the effective utilization of oily sewage is provided by laboratory experiments, such as improving sewage quality through oxygen exposure by air compressor, analyzing affection of oxygen on polymer viscosity of the polymer flooding sewage and the multilevel processing sewage, and optimizing the amount of oxygen exposure. And all above experiments conducted with the polymer which is manufactured by sewage. The results show that the best amount of oxygen exposure for the multilevel processing sewage is 5.6 mg/L with viscosity loss rate of 4.69% and the best amount of oxygen exposure for the polymer flooding sewage is 7.2 mg/L with viscosity loss rate of 11.45%. Therefore, the viscosity stability of polymer solution diluted by oily sewage can be largely improved using this technology .
