• W1969940980 abstract "Summary Polymer-flooding technology has been used widely in the Daqing oil field of China in recent years. To maintain the viscosity of a polymer solution, fresh water typically is used to confect the polymer solution instead of produced water. In doing so, a problem emerges--the produced water cannot be injected completely into the stratum. The superfluous produced water has to be treated to meet the requirements of discharge, which increases the cost of oil production. In this study, the produced water is desalinated through the implementation of of an electrodialysis principle. A set of experimental equipment that can desalinate produced water at a capacity of 300 m3/d was established at a produced-water-treatment station in the Daqing oil field. The experiment's results indicate that the total salinity of desalinated produced water can be less than 1000 mg/L. The polymer solution confected with desalinated produced water has more statistically significant characteristics than fresh water in that the viscosity increases by 63.5% and the recovery rate increases by 4.5%. This experimental study will be beneficial to keeping the balance of oily-water production and injection in oil fields. This technology for produced-water desalination will have better application prospects in the polymer-flooding process. Introduction In crude-oil extraction, water can be injected into the stratum to drive the crude oil out. This is termed often as the water-flooding process. The oil content will decrease after water-flooding is operated for some time. To improve oil recovery, polymer flooding (injected water that contains polymer) will be used subsequently, a process called enhanced oil recovery (Wang et al. 1999). Polymer-flooding technology has been used widely in the Daqing oil field of China in recent years. The oil production by polymer flooding in the Daqing oil field reached 10,000,000 tons in 2006, which is approxiamtely one-fourth of the total annual oil production. In the waterflooding process, the oily water produced from oil wells (produced water) is used to inject back into the stratum after being treated. This is beneficial to maintaining the balance of water injection and production. The produced water has a high total salinity (TS), ranging usually from 4,000 to 5,000 mg/L in the Daqing oil field. The metallic ions dissolved in the produced water, such as Ca2+, Mg2+, Na+, and K+ will result in the degradation of polymer, thus lowering the viscosity of the polymer solution. Therefore, the produced water cannot be used appropriately directly for polymer-solution confecting. To maintain the viscosity of the polymer solution, fresh water is used to confect polymer solution instead of produced water. However, a severe problem is generated: The produced water cannot be injected into the stratum thoroughly. The superfluous produced water must be treated to meet the requirements of discharge, which will increase the cost of oil production. Furthermore, the expense of buying fresh water is an additional cost burden for petroleum companies (Hu et al. 1997). In this study, the researchers attempt to desalinate the produced water through the implementation of the electrodialysis principle. A set of experimental equipment that can generate desalinated produced water at 300 m3/d was operated at a polymer-flooding produced-water-treatment station in the Daqing oil field. Its performance was evaluated. The characteristics of polymer solution confected with desalinated water were then analyzed in a laboratory." @default.
