| 摘 要： | 利用有机玻璃浸没在盐水中的办法模拟油水分布, 实验研究了不同流体分布下的等效电阻率。结果表明, 电阻率和油水分布的对应关系是非唯一的, 因此, 由井间电磁成像反演油水分布时, 必须寻求电阻率所对应的最可几分布。通过电阻的串、并联理论, 分析了流体分布对电阻率的影响, 并用数值模拟的方法研究了不同分布情况下的电场, 直观说明等效电阻率的差别。

| Abstract: | In order to simulate and control the distribution of oil and water, the authors used organic glass in place of oil. Experiments show that the relationship between electric resistivity and fluid distribution is not unique. This means that the most probability of fluid distribution must be found out when the inversion of crosshole electromagnetic imaging is done. The influence of fluid distribution upon electric resistivity is theoretically analyzed with the model of resistance in serial and parallel and numerically simulated with the ANSYS software, which gives a clear explanation of the experiment. |
