影响二元乳状液分水速度的研究

Research of water freed from binary emulsions

二元驱油剂的化学成分及其含量是影响二元乳状液分水速度的重要因素。实验从组成二元驱油剂的主要成分及含量出发,利用反映油水界面性质的参数-界面黏度、界面弹性模量、界面黏性模量、界面张力,研究了相同条件下不同相对分子质量聚合物、不同浓度聚合物、不同浓度表面活性剂的二元乳状液分水速度的差异。结合分散相液膜强度理论分析了影响二元乳状液分水速度的内在机理。

Chemical composition and content of binary combination flooding are important for water freed from binary emulsions. Taking the main component and content into account,the experiment used the nature of the oil-water interface-interfacial viscosity,interfacial elasticity modulus, interfacial viscous modulus,interfacial tension, researched the differences of water freed from binary emulsions,in under the same conditions but different molecular weights polymers,different concentrations of polymers and different concentrations of the surfactant.It analyzes the internal mechanism of water freed from binary emulsions with dispersed phase liquid film strength theory.
