A Study of Properties of Dilute Polymer Systems Prepared with Polymer-Bearing Wastewater

Abstract:

Isoconcentration flooding systems were prepared, their viscosity, shearing resistance, viscoelasticity, stability and molecule clew size were measured and the impact of polymer-bearing wastewater on polymer performance was determined in order to study the impact of polymer systems prepared with polymer-bearing wastewater on polymer performance in the polymer flooding process of Daqing oilfield. The result indicates: at the same preparation concentration, the storage modulus, loss modulus, viscosity stability, molecule clew size and shearing resistance of polymer solution systems are increased with increase in the polymer concentration in wastewater, the properties of a fresh water system are better than those of a wastewater system, the properties of a physicochemical wastewater system are better than those of a biochemical wastewater system, and the residual polymers in sewage have good viscosity increasing capacity. Therefore, polymer-bearing wastewater improves the properties of polymer systems to a certain degree and can be used as water for polymer system preparation.
