| 中文摘要: |
| 近年来，超声技术已被应用于采油工程中，在油井解堵、水井增注等方面发挥了重要的作用．针对我国大部分油田采用注水开发的实际，本文实验研究了超声波对多孔介质中油、水两相流动的影响．实验采用的多孔介质为人造石英砂岩，渗流液体为油和水．实验结果表明：超声波作用能够改善油水的流态，提高水驱采收率，并降低采出液的含水率． |
| 英文摘要: |
| in recent years, the ultrasonic technique has been used in oil production and become an important measure for damage removal of oil wells and injection-rate increase of injection wells. This paper reports the experimental study on the effect of ultrasound on the two-phase flow through porous media. The porous media used are man-made sandstones and the penetrating liquids are oil and water.From the experiments, we can draw conclusions that ultrasonic stimulation can improve the flowing performance of oil and water,increase oil recovery and reduce the producing water cut. |
