Optimization of parameters for enhancing injection by magnetic treatment in Gudong Oilfield were studied by orthogonal test, with magnetic induction strength, peak number, treatment times and flow velocity as effective factors, and membrane filtration coefficient and transparency index as targets. The test was carried out according to orthogonal table L16(44). In addition, single factor tests were made, taking the scale solubility and oil-water interfacial tension as the targets. According to the testing results, the optimal parameters of enhancing injection by magnetic treatment for Yellow River water and reinjected waste water were found. The magnetic treatment can be used in two stages. One is used as magnetic filter on the surface, and the other is used as injection enhancer in the well. Good results in field test were obtained.
