Research and Application of the Technology to Increase Viscosity and Viscosity Retention for Polymer Solution Prepared With Oilfield Wastewater

Yongqiang PAN

Abstract


Large amounts of wastewater has been produced during the development of oilfield production, furthermore, plenty of freshwater has been consumed to prepare polymer solution. This paper take a type of Shengli oilfield produced water as the research object. The combined technology of biological oxidation and biological competition was developed and tested to treat produced water. Biological oxidation technology can remove COD and hydrogen sulfide effectively. The removal efficiency is above 65% and 100% respectively. Viscosity of polymer solution (the concentration was 1,700 mg/L) prepared with this water is above 30 mPa·s. Biological competition technology can weaken SRB activity considerably. The viscosity of the polymer solution can be maintained above 20 mPa·s for more than 14 days, which meet the production standard. Application of the technology, which can not only save fresh water, but also reducing pollution discharge, has significant social and economic benefits.
