中文摘要：

在有 14.9， 5.03 和 2.05 μm 的直径的吸水、恐水病的微试管的 deionized 水的流动特征试验性地被调查。结果显示在有 14.9 μm 的直径的微试管的 deionized 水的流动特征与古典 Hagen-Poiseuille ( H-P )方程一致，要不是有更小的直径的吸水、恐水病的微试管，结果从常规理论的预言显示出重要离开，并且当雷纳兹数字减少，差异被微试管和增加的 wettability 影响。而且，在核心的液体的流动是在无数的微米大小的毛孔喉咙的流动的宏观的思考，在毛孔喉咙的微规模流动上的 wettability 的影响将引起在核心特征的渗出物的变化。因此，通过有不同 wettabilities 的核心的盐水的流动实验被进行。结果证明 wettability 在核心和微试管对水流动施加类似的影响。

英文摘要：

The flow characteristics of deionized water in hydrophilic and hydrophobic microtubes with diameters of 14.9, 5.03 and 2.05 μm are investigated experimentally. The results indicate that the flow characteristics of deionized water in microtubes with diameter of 14.9 μm are in agreement with the classical Hagen-Poiseuille （H-P） equation, but for hydrophilic and hydrophobic microtubes with smaller diameters, the results show significant departure from the prediction of conventional theory, and the discrepancies are influenced by wettability of the microtubes and increase as the Reynolds numbers decrease. Besides, flows of fluid in cores are the macroscopic reflection of flows in countless mi- cron-sized pore throats, the influence of wettability on microscale flow in pore throats will cause the change of seepage characteristic in cores. Therefore, flow experiments of brine through cores with different wettabilities are conducted. The results demonstrate that wettability exerts similar influence on water flows in cores and microtubes.
