驱油两亲聚合物及其分离组分的乳化规律研究
Study on the emulsification rules of an amphiphilic polymer and its separated components for oil displacement
摘要
Abstract
The emulsification and mechanism of an amphiphilic polymer and its separated components for oil displacement were studied by stability analyzer,opticle microscope,laser granulometer,interface tensiometer and rheometer.The results show that the molecular structures of the amphiphilic polymer and its different separated components are similar,but the contents of hydrophobic groups in different components are different.Compared with the small molecule component,the macromolecule component has weaker interfacial activity and larger droplet size of emulsion.However,the droplet migration rate is lower due to its high viscoelasticity,which improvesthe stability of emulsion.Under the synergistic effect of different components,the amphiphilic polymer for oil displacement has strong interfacial activity and its emulsion has the smallest droplet size.And the viscoelasticity of the emulsion is moderate and stable,which caues the lowest droplet migration rate and highest stability of emulsion.关键词
