According to the structure and principle of electromagnetic oil production equipment, the distribution situation of the magnetic field of the device has been analysed and computed, the calculation formula of the relevant parameters (the Intensity of Magnetic Induction B , Inductance L ) to the magnetic field has been derived , carry on calculation of magnetic force and sport analysis of characteristic of the electromagnetic oil production equipment at the same time.
The study showed that the liquidity index of the oil systems increased and the consistency index decreased by means of magnetic treatment. The optimum magnetic induction strength was in the range of 30-60 mT.
The results show that the magnetic field can promote the formation of Fe3O4 and the shuffle of self corrosion potential,and moreover,it can greatly affect the weighting rate of corrosion product. However,they have an extremum relationship with magnetic induction intensity.
