摘要
在实验室条件下，采用微观透明孔隙模型，从微观的角度研究了和电场对水驱油效率的影响，实验结果表明，静电场作用可以提高水驱油效率和采收率，实验中发现了桥接现象，这是静电场提高采收率的机理之一．
The effects of electrostatic fields on waterflooding efficiency were studied experimentally by using microscopic transparent pore models. The experiments showed that acting of electrostatic fields can improve waterflooding efficiency and enhance oil recovery.The electrostatic-field intensity affects waterflooding efficiency greatly. The phenomenon of bridge-linkage founded in the experiments is one of the mechanisms of EOR by the action of eletrostatic fields. .
