Researching Of The Technology Of Enhancing Recovery By Impose Electricity On Oil-layer

It is a new technology to enhance oil recovery by DC electric field methods, Due to the difference among rock, oil and brine,the physics field affects media, which is saturated liquid. The electrochemistry and electromotion phenomena such as electroosmosis and electrophoresis will change oil-water flowing in reservoir pore under electric field. Mathematical models to described one-phase fluid flow in fractured-vuggy media under electric field are established and the finite element equations of numerical models are derived in this dissertation. To design of rectifier circuit, simulation using Matlab software, application will be the DC capacitor filter inductor, simulation has been a smooth waveform, flooding added to meet the requirements of DC electric field. The conclusions in this paper are the theoretical basis of enhancing oil recovery of fractured-vuggy reservoir by DC electric field methods. And it is also make sense to enhancing oil recovery of fractured-vuggy reservoir by DC electric field methods.
