| Abstract: | Mathematical model to describe one-phase seepage mechanism in fractured-vug under electric field was established,and the numerical model of finite element equations was derived,including investigation into the distributions of velocity,pressure and potential in the fractured vug based on COMSOL Multiphysics software and the design of rectifying circuit simulated with Matlab software.The results show that the external DC electric field can increase the fluid velocity in the fractured vug and means great to enhance oil recovery rate of fractured-vuggy reservoirs. |
