Abstract

The oilfield sewage from chemical flooding was analysed in this paper. It showed that the sewage contained high concentration of suspended solids, organic acrylamide polymer, multivalent metal ions. IR and Electron microscope measurement showed the value of suspended solids measured by membrane filtering method was much higher than the real value due to polymer absorption and plugging on membrane. The suspended solids in filtered sewage increased due to formation of fine inorganic scale and colloidal particles under certain conditions. The zeta potential showed the sewage was much negatively charged. At pH value 3~4, the zeta potential of sewage shifted to -5.0mv quickly and much precipitate of polymer gel appeared in sewage. Above all, the negatively charged polymer and high viscosity of sewage played an important role in dispersing and stabilizing suspended solids.
