直流电处理油层提高采收率实验研究

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

  • 摘要: 实验研究了直流电场作用于油层的水驱油效果,当生产井为正极、注入井为负极时,直流电位梯度的作用使油相渗透率增加、水相渗透率降低,水油比降低、采收率增加。油相渗透率及采收率与电位梯度成正比。研究结果及国外成功实例表明该技术有广阔的应用前景。

     

    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.
