摘要
通过建立模拟单孔隙喉道的毛细管实验模型,研究了表面活性剂启动喉道残余油的微观机理。研究结果表明,毛管力变化产生的油滴变形以及Marangoni对流产生界面扰动使残余油自发乳化导致油滴通过喉道时的阻力减小,甚至乳化成小于喉道半径的乳状液,在不受毛细管阻力的情况下通过喉道。
Through the establishment of experimental model of simulating the capillary pore throats,it studied micro-mechanism of surfactant displacing residual oil.The research results showed that oil droplet deformation by capillary pressure and interface perturbations by Marangoni convection make the residual oil emulsification spontaneous.It resulted in decrease of oil drops through the throat of the resistance and made it emulsified into smaller than the throat radius of emulsions and throughed the throat without capillary resistance.
