Abstract

Abstract: This study addresses the problem of unbalanced water injection and production in a ground system. Based on the existence of insufficient wastewater sources following deep filtration treatments and lack of precious clean water sources in oilfields, this study considers the technology of a two-stage deep filtration treatment that utilizes "double-layered filter material+ three-level graded filter material" after ordinary treatment of polymer-containing wastewater. The advanced treatment technology of two-stage filtration considers variations in polymer concentration and its correlation with filtration process parameters. A numerical simulation is conducted to describe the aggregated distribution characteristics of oil beads and suspended particles in the flow field of the deep filtration process. This is necessary to determine changes in the content of oil and suspended solids in filtered water following deep filtration. The results show that it is feasible to control the water quality indices of oil and the content of suspended solids to within 5.00 mg/L by performing deep filtration on the polymer-containing wastewater. An optimized technical boundary relationship map of the deep filtration technology for polymer-containing wastewater can be used to enhance the indicators and efficiency of its treatment. The operational load and stability of the polymer-containing wastewater treatment process can also be ensured.
