Abstract
The effectsof DC electric field strength and direction on oil-water relative permeability and the influence mechanism in reservoir were studied and analysed.The results of experiments indicated that, with the application of external electric field, the core samplesbecomes more hydrohilic, irreducible water saturation increasesand residual oil saturation decreases. Meanwhile, oil relative permeability increases and water relative permeability decreases with increasingof the strength of external electric field. It is demonstrated as well that the different seepage flow behaviors, the structure change of double-electric-layer surface and the electric-viscous effect of polar and non-polar phaseare the main factors influencingoil-water relative permeability.
