An Experimental Study of Using Direct Current on Oil Bearing Formation to Enhance Recovery Efficiency

    Abstract
  • The electric field of direct current acting on oilbearing formation had been studied,results show that oilphase peameability and recovery effciency are directlyproportional to potential gradient, but water phasepermeability and water oil ratio reducing,when producingwell has been as anode water injection well as cathode.Application of the technique has a bright future. in HenanOilfield and even in eastern China.
