| 摘 要： | 油层的润湿性对孔陈中流体的分布具有重要的影响作用.驱油实验前进行的洗油过程所用的甲苯是亲油的,这必然会改变岩心的润湿性;同时,水对岩心长时间的冲洗也可能影响岩心的润湿性.为了研究这些因素对润湿性的影响水平,采用德国Dataphysics公司生产的视频光学接触角测量仪,结合水洗油实验,研究了洗油过程中岩心润湿性的变化趋势...

| Abstract: | The wettability of oil layers shows an important effect for the fluid distribution in pores.Washing oil before flooding experiment will change the core wettability because toluene,which is hydrophobic,is used in the process of washing oil.At the same time,the long-time flush of water on cores will affect the wettability of cores.The changing rules of wettability during washing oil are studied by using the optical contact angle measuring device produced by Dataphysics Company,Germany through the combination ... |
