It can be concluded from the study that: oil always migrates from high potential area to low potential area, and the low potential area of oil is accumulation place of oil.
研究表明，石油总是由高势区向低势区运移，油势低势区是石油富集的区域。
The results show that the cell potential along fuel flow change little at high current density when low fuel or products concentration area does not appear.
结果表明：在高电流密度情况下，当燃料沿燃料通道方向流动未出现低燃料浓度区或产物浓度区时，电池电势在燃料流动方向上变化不大；
After polymer flooding and polymer cross link micro gel flooding, the residual oil mainly distributes in middle and low permeable reservoirs. This is the potential area of EOR.
在聚合物驱及聚合物交联微凝胶驱后，地层内剩余油主要分布在中、低渗透层，这是进一步提高采收率的潜力所在。
