| 摘 要： | 通过电极电位模型储层电阻率变化量与地表电位变化量之间的关系,采用电位测量方法进行地下储层中稠油运移规律的动态监测。在新疆某油田"稠油油藏汽驱试验"项目中进行该方法的试验,利用汽驱过程中监测到的电位场增量变化特征推断汽驱推进方向及波及范围,根据电位相对变化量值对汽驱作用效果进行区块划分,电位变化量相对大的区块汽驱作用明显,反映该区块的采油产量较高。

| Abstract: | The authors established the relationship between the reservoir resistivity's variation and surface potential's variation based on electrodes potential model,which provides a theoretical basis for dynamic monitoring the movement pattern of viscous oil by using potential measurement method.This technique was used in a project carried in an oilfield in Xinjiang.The authors conclude the advancing direction and affect area of stream flooding by measuring the variation of electric field,delimit different regions depending on the effect of stream flooding.The region has larger variation of potential.The stream flooding's effect is more obviously,which shows the higher production of oil it should have. |
